Podcasts about GLONASS

In un'epoca in cui la connettività e la geolocalizzazione sono diventate elementi imprescindibili della quotidianità, i Sistemi di Navigazione Satellitare Globale, o più semplicemente GNSS, rappresentano un'infrastruttura tecnologica strategica senza la quale molti servizi non potrebbero esistere e aiutarci nelle attività di tutti i giorni. Ci basti pensare che dietro il semplice gesto di consultare un'app di navigazione o di ricevere un pacco acquistato online si nasconde una vastissima rete di satelliti in perfetta sinergia tra di loro che fornisce istantaneamente dati di posizionamento estremamente precisi. Ma che cosa sono i GNSS e qual è la differenza con il GPS di cui sentiamo parlare tutti i giorni? In questa puntata proviamo a capirlo.Nella sezione delle notizie parliamo dei nuovi Tutor 3.0 autostradali, dello studio del CNR per trasformare la luce in un solido e infine della missione delle sonde spaziali Voyager e di come la NASA stia cercando di allungare il più possibile la sua durata.--Indice--00:00 - Introduzione00:57 - Tutor 3.0 come deterrente più preciso in autostrada (DMove.it, Davide Fasoli)02:12 - La luce è stata trasformata in un solido (HDBlog.it, Luca Martinelli)03:20 - La NASA prolunga la missione delle Voyager (DDay.it, Matteo Gallo)05:12 - Il dualismo dei GNSS tra applicazioni civili e militari (Matteo Gallo)18:24 - Conclusione--Contatti--• www.dentrolatecnologia.it• Instagram (@dentrolatecnologia)• Telegram (@dentrolatecnologia)• YouTube (@dentrolatecnologia)• redazione@dentrolatecnologia.it--Immagini--• Foto copertina: ESA - P.

Al Capítol 58 de La nova mobilitat conversem amb Pere Molina sobre els sistemes GNSS (com el GPS, Galileo, GLONASS i BeiDou) i com aquests ens permeten situar-nos amb precisió a qualsevol punt del planeta. Què aprendràs en aquest episodi? ✅ L'origen i l'evolució dels sistemes de navegació per satèl·lit. ✅ Les aplicacions civils i militars del GNSS: des del mòbil fins als sistemes de defensa. ✅ Com funcionen les IMU (unitats de mesurament inercial) i per què són clau quan no hi ha senyal GPS.

"GPS in Deliveries" unveils the hidden layer behind the everyday use of navigation systems, exploring how GPS technology has evolved from a military tool to a global surveillance network. The episode highlights how countries like Russia and China have developed their own systems, GLONASS and BeiDou, to assert digital sovereignty and avoid dependency on the U.S. controlled GPS. It delves into the implications of geofencing and the data gathered by autonomous vehicles, raising questions about the extent of control and surveillance in modern logistics. With a nod to the film Enemy of the State, the episode leaves viewers pondering the true power of a map in the wrong hands.

Occhi puntati al cielo per la notte di San Lorenzo alla ricerca di stelle cadenti. Ma è importante ricordare che lo spazio non è solo un luogo di stelle e pianeti, ma anche di satelliti artificiali che svolgono un ruolo cruciale per il mondo dei trasporti.In questa puntata di Container, Massimo De Donato ne parla con Marco Lisi, membro del cda dell’ASI, Agenzia Spaziale Italiana.Sistemi come GPS, GLONASS, BeiDou e l’europeo Galileo forniscono dati di posizionamento precisi che, integrati con altre tecnologie, hanno rivoluzionato il settore dei trasporti. Galileo in particolare garantisce una precisione altissima e un posizionamento su scala decimetrica.Grazie ai satelliti è possibile ottimizzare i percorsi, riducendo consumi di carburante ed emissioni inquinanti; gestire le flotte, monitorando in tempo reale la posizione dei veicoli e pianificando le attività; aumentare la sicurezza.

This week we talk about APT28, spoofing, and hybrid warfare.We also discuss the Baltics, Tartu airport, and hacking.Recommended Book: The Middle Passage by James HollisTranscriptIn early May of 2024, the German government formally blamed a Russian hacking group called APT28 for hacking members of the governing German Social Democratic Party in 2023, and warned of unnamed consequences.Those consequences may apply just to APT28, which is also sometimes called "Fancy Bear," or they may apply to the Russian government, as like many Russia-based hacking groups, APT28 often operates hand-in-glove with the Russian military intelligence service, which allows the Russian government to deny involvement in all sorts of attacks on all sorts of targets, while covertly funding and directing the actions of these groups.APT28 reportedly also launched attacks against German defense, aerospace, and information technology companies, alongside other business entities and agencies involved, even tangentially, with Ukraine and its defense measures against Russia's invasion.This hacking effort allegedly began in early 2022, shortly after Russia began its full-scale invasion of Ukraine, and the head of the Russian embassy in Germany has been summoned to account for these accusations—though based on prior attacks and allegations related to them by Russia's intelligence agencies, and the hacking groups it uses as proxies, that summoning is unlikely to result in anything beyond a demonstration of anger on the part of the German government, formally registered with Russia's representative in Berlin.For its part, Russia's government has said that it was in no way involved in any incidents of the kind the German government describes, though Germany's government seems pretty confident in their assessment on this, at this point, having waited a fair while to make this accusation, and utilizing its partnerships with the US, UK, Canada, and New Zealand to confirm attribution.This accusation has been leveled amidst of wave of similar attacks, also allegedly by Russia and its proxies, against other targets in the EU and NATO—including but not limited to the Czech Republic, Lithuania, Poland, Slovakia, and Sweden.Many of these attacks have apparently made use of an at-the-time unknown security flaw in Microsoft software that gave them access to compromised email accounts for long periods of time, allowing them to, among other things, scoop up intelligence reports from folks in the know in these countries, sifting their messages for data that would help Russia's forces in Ukraine.This group, and other Russia GRU, their intelligence service, proxies, have reportedly targeted government and critical infrastructure targets in at least 10 NATO countries since the fourth quarter of 2023, alone, according to analysis by Palo Alto Networks, and experts in this space have said they're concerned these sorts of attacks, while often oriented toward intelligence-gleaning and at times embarrassing their targets, may also be part of a larger effort to weaken and even hobble intelligence, military, and critical infrastructure networks in regional nations, which could, over time, reduce stability in these countries, increase extremism, and possibly prevent them from defending themselves and their neighbors in the event of a more formal attack by Russian forces.What I'd like to talk about today is another sort of attack, allegedly also launched by Russia against their neighbors in this part of the world, but this one a little less well-reported-upon, at this point, despite it potentially being even more broadly impactful.—The Global Positioning System, or GPS, was originally developed in 1973 by the US Department of Defense. Its first satellite was launched in 1978, and its initial, complete constellation of 24 satellites were in orbit and functional in 1993.This satellite network's full functionality was only available to the US military until 2000, when then-President Bill Clinton announced that it would be opened up for civilian use, as well.This allowed aviation and similar industries to start using it on the vehicles and other assets, and normal, everyday people were thenceforth able to buy devices that tapped this network to help them figure out where they were in the world, and get to and from wherever they wanted to go.A high-level explanation of how GPS works is that all of these satellites contain atomic clocks that are incredibly stable and which remain synchronized with each other, all showing the exact same, very precise time. These satellites broadcast signals that indicate what time their clocks currently read.GPS devices, as long as they can connect to the signals broadcast by a few of these satellites, can figure out where they're located by noting the tiny differences in the time between these broadcasts: signals from satellites that are further away will take longer to arrive, and that time difference will be noted by a given device, which then allows it to triangulate a geolocation based on the distance between the device and those several satellites.This is a simple concept that has created in a world in which most personal electronic devices now contain the right hardware and software to tap these satellite signals, compute these distances, and casually place us—via our smartphones, cars, computers, watches, etc—on the world map, in a highly accurate fashion.This type of technology has proven to be so useful that even before it was made available for civilian use, catalyzing the world that we live in today, other governments were already investing in their own satellite networks, most predicated on the same general concept; they wanted to own their own constellation of satellites and technologies, though, just in case, because the GPS network could theoretically be locked down by the US government at some point, and because they wanted to make sure they had their own militarizable version of the tech, should they need it.There are also flaws in the US GPS system that make it less ideal for some use-cases and in some parts of the world, so some GPS copycats fill in the blanks on some of those flaws, while others operate better at some latitudes than vanilla GPS does.All of which brings us to recent troubles that the global aviation industry has had in some parts of the world, related to their flight tracking systems.Most modern aircraft use some kind of global navigation satellite system, which includes GPS, but also Europe's Galileo, Russia's GLONASS, and China's BeiDou, among other competitors.These signals can sometimes be interrupted or made fuzzy by natural phenomena, like solar flares and the weather, and all of these systems have their own peculiarities and flaws, and sometimes the hardware systems they use to lock onto these signals, or the software they use to compute a location based on them, will go haywire for normal, tech-misbehaving reasons.Beginning in the 1990s, though, we began to see electronic countermeasures oriented toward messing with these global navigation satellite system technologies.These technologies, often called satellite navigation deceivers, are used by pretty much every government on the planet, alongside a slew of nongovernment actors that engage in military or terrorist activities, and they operate using a variety of jamming methods, but most common is basically throwing out a bunch of signals that look like GPS or other navigation system signals, and this has the practical effect of rendering these gadgets unusable, because they don't know which signal is legit and which is garbage; a bit like blasting loud noises to keep people from talking to each other, messing with their communication capacity.It's also possible to engage in what's called GPS Spoofing, which means instead of throwing out gobs of garbage signals, you actually send just a few signals that are intended to look legit and to be accepted by, for instance, a plane's GPS device, which then makes the aircraft's navigation systems think the plane is somewhere other than it is—maybe just a little off, maybe on the other side of the planet.Notably, neither of these sorts of attacks are actually that hard to pull off anymore, and it's possible to build a GPS-jamming device at home, if you really want to, though spoofing is a fair bit more difficult. Also worth knowing is that while making your own jammer is absolutely frowned upon by most governments, and it's actually illegal in the US and UK, across most of the world it's kind of a Wild West in this regard, and you can generally get away with making one if you want to, though there's a chance you'd still be arrested if you caused any real trouble with it.And it is possible to cause trouble with these things: most pilots and crew are aware of how these devices work and can watch for their effects, using backup tools to keep tabs on their locations when they need to; but using those backup tools requires a lot more effort and attention, and there's a chance that if they're hit by these issues at a bad moment, when they're distracted by other things, or when they're coming in for a landing or attempting to navigate safely around another aircraft, that could present a dangerous situation.That's why, until May 31, at the minimum, Finnair will no longer be flying to Tartu airport—which is a very small airport in Estonia, but it's home to the Baltic Defense College, which is one of NATO's educational hubs, and losing a daily flight to Tartu (the only daily flight at this particular airport) from Helsinki, will disconnect this area, via plane, at least, from the rest of Europe, which is inconvenient and embarrassing.This daily flight was cancelled because of ongoing disruptions to the airport's GPS system, which was previously an on-and-off sort of thing, but which, since 2022, when Russia launched its full-scale invasion of Ukraine, has become a lot worse. And Tartu relies exclusively on GPS for planes landing at the airport, and thus doesn't have another fallback system, if GPS fails at a vital, dangerous moment.This is a running theme throughout the Baltic region, an area populated by now-democratic NATO members that were formerly part of the Soviet Union, and which are considered to be at risk of a Russian invasion or other sort of attack if the invasion of Ukraine goes Russia's way.Almost all aircraft flying through this area have experienced GPS-jamming issues since 2022, and though that Finnair flight is the only one to have been cancelled as a result of all this jamming, so far, there are concerns that this could really scramble travel and shipping in the region, as it's making all flying in the area that much more risky on a continuous basis.Finland's government is framing this jamming as part of a hybrid warfare effort on Russia's part—alongside other hybrid efforts, like bussing migrants to Finland's borders in order to strain national coffers and nudge politics toward reactionary extremes.Some other nations are thinking along the same lines, though there's a chance that, rather than this jamming representing an intentional assault on these neighboring nations, it may actually be something closer to overflow from other, nearby jamming activities: Russia jamming GPS signals in Ukraine, for instance, or the governance of the Kaliningrad region, which is a Russian enclave separated from the rest of Russia and surrounded by Poland and Lithuania, engaging in their own, localized jamming, and those signals are then picked up across national borders, because that's how these signals work—just like sound can travel further than you might intend.It's possible we're seeing a bit of both here, overflow from that huge regional conflict, but also intentional jabs meant to make life more difficult for NATO nations, stressing their systems and costing them money and other resources, while also maybe testing the region's capacity to cope with such GPS disruptions and blackouts in the event of a potential future conflict.Another point worth making here, though, is that we see a lot of this sort of behavior in conflict zones, globally.FlightRadar24 recently introduced a live GPS jamming map to keep track of this sort of thing, and as of the day I'm recording this, alongside these consistent irregularities in the Baltic region, Ukraine, and parts of Eastern Europe, there's jamming occurring in the Middle East, near Israel, throughout Turkey, which has ongoing conflicts with insurgents in the afflicted areas, a portion of Moldova that is attempting to break away with the support of Russia, similar to what happened in Ukraine back in 2014, a northern portion of India where the Indian government has an ongoing conflict with separatists, and in Myanmar, where the military government is embroiled in fighting with a variety of groups that have unified to overthrow them.This has become common in conflict zones over the past few decades, then, as those who want to deny this data, and the capabilities it grants, to their enemies tend to blanket the relevant airwaves with disruptive noise or incorrect location information, rendering the GPS and similar networks less useful or entirely useless thereabouts.In Ukraine, the military has already worked out ways around this noise and false information, incorporating alternative navigation systems into their infrastructure, allowing them to use whichever one is the most accurate at any given moment.And it's likely, especially if this dynamic continues, which it probably will, as again, this is a fairly easy thing to accomplish, it's likely that spreading out and becoming less reliant on just one navigation system will probably become more common, or possibly even the de facto setup, which will be beneficial in the sense that each of these systems has its own pros and cons, but perhaps less so in that more satellites will be necessary to keep that larger, multi-model network operating at full capacity, and that'll make it more expensive to operate these systems, while also creating more opportunities for satellite collisions up in the relevant orbit—an orbit that's becoming increasingly crowded, and which is already packed with an abundance of no longer operational craft that must be avoided and operated-around.Show

Vært: Henrik Heide Medvirkende: Ole Mørk Lauridsen, civilingeniør, adjungeret professor ved DTU og tidligere udviklingsdirektør i Tele Danmark og teknologidirektør hos Terma Laurids Hovgaard, elektronikjournalist, Ingeniøren Klip: Søren Rask Petersen Det er nærmest en selvfølge, at satellitter hjælper os gennem hverdagen og jobbet. GPS er der bare med præcis, stabil og ikke mindst billig position, højde og tidsangivelse. Vi har den i mobilen og bilen, og overalt bruger vi GPS til navigation, opmåling og tidssynkronisering, eksempelvis i finans- og telesektoren. Men lige så effektivt systemet er, lige så sårbart er satellitsignalerne, der rejser mere end 20.000 kilometer, før de hjælper os på vej. Med simpel og tilgængelig elektronik kan enhver med en smule teknisk indsigt gøre livet surt for fly og skibe, fortæller tidligere teknologidirektør hos Terma, Ole Mørk Lauridsen, der i dag underviser på DTU: »Vi skal jo forstå, at vores GPS-system, det europæiske Galileo og det russiske Glonass jo alle er baseret på de samme internationale aftaler for, hvordan man bruger det samme frekvensområde – bare med forskellige modulationsformer,« fortæller han til denne uges Transformator. Det er ganske simpelt at forstyrre de store, komplekse satellitsystemer med simpel, elektronisk hjemmesløjd, forklarer Ole Mørk Lauridsen: »Man kan bare tage udstyr, som i forvejen anvendes til at skaffe lokal GPS-dækning i lufthavne eller store servicegarager. Og så modificerer man det lidt og sætter en større udgangsforstærker på. Det er jo nemt tilgængeligt udstyr. For 10.000 kroner har du udstyr, der kan forstyrre langt væk,« siger han. »Og her taler jeg altså om den intelligente form for forstyrrelse inde på protokolniveau med signaler, der kan definere, hvilket af de tre systemer det generer. Det betyder, at man med spoofing kan ramme selektivt det ene eller det andet af de tre systemer. At man med andre ord kan genere GPS uden at genere Glonass.« »Hvis man vil sende støj og genere alle tre systemer på samme tid, så er det meget simple sendere det skal til det frekvensområde. Det kan enhver kortbølgeamatør lave på en eftermiddag,« siger Ole Mørk Lauritsen. Forstyrrelser fortæller hvad der er på vej Forstyrrelserne på GPS-signalet ser ud til at komme på både tilfældige tidspunkter og med fast rytme. Et af de områder, der har været udsat for gentagne forstyrrelser, svarer til det område af Sydsverige, der ifølge det svenske forsvar vil blive angrebet først ved udbrud af krig. At signalerne kommer og går, er der en oplagt forklaring på, mener Ole Mørk Lauritsen: »Det giver os en ide om, hvad der er på vej. Det er garanteret med vilje, at de ikke forstyrrer hele tiden. For så lever vi med at bruge GPS. Hvis de forstyrrede os hele tiden, ville vi hurtigt finde på at falde tilbage på Dekka, Loran eller andre gamle systemer,« siger han. »Jeg tror man er nødt til at gøre sig klart, at den offentlige infrastruktur, den skal kontrolleres på en måde, så den kan køre for sig selv.« Ingeniør byggede modstandsbevægelsens radio Transformator møder Ole Mørk Lauritsen på Danmarks første kystradiostation, OXA, der ligger på Flådestation Holmen og rummer radioudstyr tilbage til før Anden Verdenskrig. Elektronik fra en tid, hvor krigens parter fandt hver deres vej til sikker telekommunikation. Under krigen var en del af radioudstyret hjemmebygget af modstandsbevægelsens egne folk. Blandt andet en ingeniør fra B&O, der byggede en lille, sikker radio, der langt overgik de indviklede, britiske radioer. Og han anvendte blot dele fra almindelige konsum-radiomodtagere. Hør hele historien om den elektroniske krigsførelse i nutiden og under besættelsen i denne uges Transformator, hvor vi forklarer jamming og spoofing. Men hvor vi også kommer med forslag på en løsning.

Il se déplace à environ 11'000km/h, à une altitude d'environ 20'000km au-dessus de nos têtes. Il fait le tour complet de la planète en environ 12h, et n'a pas le droit de se tromper dans sa mesure du temps de 1 nanoseconde durant le tour de la planète. Lui, c'est le satellite de la constellation GPS. Ces objets de 900kg constituent le cœur du système de positionnement mondial. Comme ses frères et sœurs d'autres constellations comme Glonass, Galileo ou Beidu, il embarque deux horloges atomiques pour reste à l'heure. Vous l'aurez compris, dans l'épisode du jour, on parle de mesure du temps, de positionnement GNSS et de précision de cet ensemble complexe qui nous permet de nous géolocaliser partout sur la planète.

GB2RS News Sunday the 15th of October 2023 The news headlines: • RSGB Construction Competition • New chair of the RSGB's Exams and Syllabus Group • RSGB 2023 Convention The RSGB recognises the importance of construction as a key element of amateur radio, whether that is using traditional construction skills or is a software or systems engineering project. The Society has launched its 2024 Construction Competition and the deadline for entries is the 1st of March 2024. To enable members across the country, and even the world, to enter, entries will be judged over the internet rather than in person. This year a new category called ‘Antennas' has been introduced so there are five categories you can enter: Beginners; Construction Excellence; Innovation; Software and Systems; and Antennas. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition The RSGB is delighted to welcome Andrew Lenton, G8UUG as the new Chair of the Exams and Syllabus Review Group. The Society would also like to thank Donard de Cogan, M0KRK for his hard work and dedication, including chairing the Group for the past three years. You can contact Andrew via esrg.chair@rsgb.org.uk The RSGB 2023 Convention takes place over both days this weekend. There is a fantastic range of presentations on a variety of amateur radio topics. If you haven't already booked, you can buy day tickets on the door or join the Livestream at any time over the weekend. The Livestream contains 12 of the Convention presentations as well as exclusive interviews and additional content. We are asking radio amateurs to register for the Convention Livestream this year. Whether you are there in person, or joining radio amateurs from across the world online, make sure you are part of this major annual event. For more information about the full programme of presentations go to rsgb.org/convention and to register for the Livestream head over to rsgb.org/livestream As we get closer to the ITU World Radio Conference, WRC-23, which starts next month, the future of amateur radio, particularly the 23cm band, is of key importance. The ITU News Magazine has a feature article by IARU President Tim Ellam, VE6SH regarding amateur activity in the 23cm band. This is the topic of a challenging agenda item at the Conference which calls for measures that protect primary radio-navigation services such as Glonass and Galileo from amateur terrestrial and satellite usage. You can read the article by visiting tinyurl.com/TimVE6SH In related news, the IARU also reports that the last formal preparatory meeting ahead of the WRC on this topic was difficult and could not achieve a consensus on measures such as power and bandwidth limits, or frequency restrictions. The IARU supports further efforts and will continue to try to find a solution regarding suitable recommendations, whilst opposing the unwarranted statutory imposition of such. You can read the IARU's post on this subject via tinyurl.com/ITUR23cm  Also, you can hear the latest updates at the RSGB Convention on Sunday, in a talk by IARU expert and RSGB Microwave Manager Barry Lewis, G4SJH.  Jamboree On The Air, or JOTA, is an annual event in which Scouts and Guides all over the world communicate with each other via amateur radio.

On Thursday the 19th of October, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. On Sunday the 22nd of October, the 50MHz Affiliated Societies Contest runs from 0900 to 1300UTC. Using all modes on the 6m band, the exchange is signal report, serial number and locator. The Worked All Germany Contest starts at 1500UTC on Saturday the 21st of October and ends at 1500UTC on Sunday the 22nd of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. German stations also send their DOK reference. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of October 2023 We had a period of low geomagnetic disturbance last week, which allowed the upper HF bands to shine. There were lots of reports of DX being worked on the 10m band as the Kp Index sat mainly in the ones and twos, with a maximum of Kp 3.33 for one three-hour period on the 9th. The Solar Flux Index, or SFI, also remained in the 150s and 160s, hitting a maximum of 166 on the 9th. All in all, these were very good conditions for high-band DXing, especially at this optimum time in the calendar. As promised last week, let's take a look at HF paths from the UK to the W8S Swains Island DXpedition in the South Pacific. The good news is that operations are in full swing and are being spotted daily on the DX Cluster. At a distance of approximately 9,500 miles from the UK on the short-path, and 15,300 miles on the long-path, it's quite a distance for signals to traverse. The short-path beam heading you need to select is a polar path at 350 degrees, and for long-path 169 degrees. The best openings to Swains from the UK start on the 20m band from about 0630UTC. As the morning progresses, move up in frequency until you get to the 10m band around 1000 to 1100UTC. This path should remain open until 1500 or 1600UTC, at which point you can drop down to the 12, 15 or 17m bands. Long-path openings may be a lot weaker, with a short opening on the 15m band from 0600 to 0800UTC. Then move to the 12 or 10m bands from 0700 to 0900UTC. There may also be a long-path evening opening from 1800 to 2000UTC on the 17 and 10m bands. The above predictions are for SSB and CW. You may find FT8 openings extend these times a little. For more details, and to compute your own predictions, see VOACAP.com or Proppy at soundbytes.asia/proppy This weekend, ending today the 15th, may see some geomagnetic disturbances due in part to a coronal hole. But, as long as we don't get any coronal mass ejections, this should settle after the weekend.  The Solar Flux Index is predicted to remain in the 150s with a maximum Kp index of two. If this turns out to be true, we should have a good week of DX hunting to come. And now the VHF and up propagation news The coming period of weather offers many changes, and it looks as though we have said goodbye to the warm air, with low pressure controlling events.   Just a gentle reminder to keep an eye on your antennas as this time of year can produce surprisingly rapid developments of deep low-pressure systems with associated strong winds.  Early next week, a temporary high returns to give you a chance to give those antenna supports and guys a once-over while winds are light, and leave the potential Tropo until the evenings and overnight. Incidentally, this new high is essentially a cold air high, so may not be as productive as the recent Tropo of the week just ending. The new high will probably hang around until midweek when it should migrate north to allow an easterly wind across the south. This will probably bring some showery rain along the east coast. It's possible that we may have some rain scatter from these showers. Meteor scatter is always good in October, with high random meteor rates and a number of small showers. Most notable of these is the Orionids Meteor Shower which peaks on the 22nd of October and is active until the 7th of November with an average zenithal hourly rate of around 20. Of course, aurora is also worth keeping in mind if you get any spare time! For EME operators, Moon declination is negative and falling all week, reaching minimum on Friday the 20th with corresponding shortening Moon windows. As we are now past apogee, path losses will continue to fall.  144MHz sky noise starts very high with the annular eclipse on Saturday the 14th. The following week sees it moderate, increasing to a high of over 2000 Kelvin on Thursday. And that's all from the propagation team this week.

En los últimos tiempos, y vinculada a la situación bélica que se corre en el entorno de Ucrania ha disparado el uso de un arma tecnológica que puede tener consecuencias castróficas: El hackeo o neutralización de la señal del sistema GPS con el que se mueven aviones, barcos y cualquier sistema que requiera de geolocalización está al alza, y especialmente en las zonas limítrofes e irradiantes con el conflicto es cada vez un uso más común. Con sistemas de navegación cada vez más automatizados, la confiabilidad en los sistemas de geoposicionamiento, sean GPS, Galileo o Glonass cobra vital importancia, y algunos estados no tienen ningún reparo en aprovechar tecnologías de neutralización para poner las cosas difíciles al enemigo... y de rebote a las vidas que se transportan con estos sistemas.

This week's EYE ON NPI will "Speak Friend and Enter" your wireless connectivity toolbox, it's TE's LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/en/product-highlight/t/te-connectivity-amp/lembas-lte-gnss-usb-modem) an easy-to-use full powered cellular and GPS modem designed specifically to be used with single-board Linux computers (SBCs) to add networking and location tracking with a simple plug-and-play USB connection. We bought one and popped it open - not recommended because it will void your warranty - and found inside is a Quectel EC25-AFXD module (https://www.digikey.com/en/products/detail/quectel/EC25AFXGA-128-SGAS/13278280) - an LTE Cat 4 data-only module with high speed uplink and downlink when LTE is available, and GSM/GPRS backward-compatibility for remote areas. Quectel EC25 is a series of LTE Cat 4 modules optimized specially for M2M and IoT applications. Adopting the 3GPP Rel-11 LTE technology, it delivers maximum data rates up to 150 Mbps downlink and 50 Mbps uplink. Designed in the compact and in a unified form factor, the EC25 series is compatible with Quectel multi-mode LTE Standard EC21 series/EC20-CE/EG25-G/EG21-G modules and UMTS/HSPA+ UC200A-GL module, which allows for flexible migration among them in design and manufacturing... backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage. EC25 series supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BDS, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning. The LEMBAS has a lot of little details that shows the design team focused on a high quality build and removing any obstacles to use. For example, instead of a 'USB stick' style modem that blocks all of the USB ports on your raspi, the modem uses any USB Type C cable - this also allows the user to place the LEMBAS wherever the antenna will get best reception. When we opened it up, we noticed that the board was conformal coated (https://www.digikey.com/en/products/filter/coating-grease-repair/642), so it will handle being exposed to humid air, although please note it's not rated for outdoor use. The SIM card is pre-installed but can be removed / replaced easily if a particular data service is desired. We also thought the status LEDs that appear as part of the TE logo showed a cute designer touch. One handy design decision that makes the LEMBAS easy to get started with: inside is a 2-port USB hub (https://www.digikey.com/en/products/detail/texas-instruments/TUSB4020BIPHP/5724124) so that, when plugged into USB, it shows up as both the modem interface and a small USB storage key. On that storage are all the files you need to run to install the modem interface on an Arm32 or Arm64 computer like the Raspberry Pi. This definitely solves the "to get on the internet I have to install my wireless drivers but I can't get onto the internet because I haven't installed my wireless drivers" problem. And of course, there's a GNSS inside as well, which makes this perfect for asset tracking or geo-locating projects where you need to know where the code is running from. It's ready to go in an instant and with native Linux support for cellular modems, you don't need to do any AT command noodling - use Python or node.js or whatever language your application is and open secure sockets like normal. If you've got a hankerin' for a piece of Elvish-quality technology that will let you communicate anywhere in the world, even on the top of Mt. Doom, you can pick up a TE LEMBAS LTE/GNSS USB Modem (https://www.digikey.com/short/4172bndv) from DigiKey today and it will ship to you as fast as a gigantic eagle so that you can get started tomorrow morning... right after second breakfast!

In this episode of PING, APNIC's Chief Scientist Geoff Huston discusses how Sweden built a national time distribution system and the nature of time in the modern Internet. At the RIPE86 Meeting held in Rotterdam in May of this year, Karin Ahl, the CEO of Netnod presented a talk titled “How Sweden Built a World-Leading Time Network” A central problem in time distribution on the Internet is firstly the lack of security inside the Network Time Protocol (NTP), and secondly the sources and reliability of the time information. The first problem is solved by using the newer Network Time Security (NTS) protocol which adds TLS, and the second by investment in reliable and strategically placed time distribution servers, which is the basis of the Swedish national time initiative. Geoff attended the Netnod presentation and reflects on the complex and murky history of time, and the emergence of worldwide communities that coordinate both civil time (what the time of day is, in the world) and the nature of how time is measured (how a ‘second' is defined, for example). Geoff discusses historic and current attempts to standardise time measurements (such as UT1 and UTC) — with their inherent compromises — against Earth's revolutions and rotations around the Sun. These measurements have become increasingly critical to modern technology, such as GPS.

Decisions made in the 1950s and 1970s to try and normalise the difference between monotonically increasing “UT1” time and the civil time system we know as “UTC” continue to plague the IT world, as civil time drifts (occasionally) by one second forwards (or very occasionally backwards) against UT1 -And with the emergence of more and more technology and especially satellite based systems like GPS, Bai-Dou, Galileo and GLONASS which provide time, the need to finalise the relative status of each time model becomes greater.

El megaproblema de las megaconstelaciones de las megaempresas Una constelación de satélites es un grupo de satélites artificiales que trabajan coordinadamente. El ejemplo más conocido son las de posicionamiento, como el Global Positioning System (GPS) y sus análogos europeo (Galileo) y ruso (GLONASS). Hasta ahora estas eran las mayores existentes, con 31, 22 y 24 satélites en activo respectivamente. Sin embargo, recientemente varias empresas han manifestado su interés por crear auténticas megaconstelaciones de miles de satélites: Space-X con 30.000, Amazon con 3.000, OneWeb con 48.000, la agencia espacial china… ¡hasta Boeing y Samsung planean unirse a la fiesta! De lograr sus intenciones, en la próxima década podríamos tener más de 100.000 satélites orbitando la Tierra.

El gobierno ruso planteó la posibilidad de instalar en México su sistema de navegación satelital Glonass, pero el gobierno de nuestro país negó que esto fuera a suceder. ¿Qué hay detrás de estas versiones encontradas?Con entrevistas a: Beata Wojna, Almudena Azcárate y Daniel Porras. Hosted on Acast. See acast.com/privacy for more information.

Desde hace unos días, se ha desatado una controversia sobre el acuerdo firmado entre México y Rusia. Supuestamente, el gobierno mexicano le abrió la puerta al sistema de geolocalización ruso: Glonass. Fausto Pretelin, analista internacional y columnista de El Economista, nos habla al respecto. En otros temas: Vladimir Putin confirma ataque masivo con armas de largo alcance contra Ucrania.

Jimmy Herrera, impulsor de Agencia Espacial Mexicana

En entrevista Fausto Pretelin, internacionalista, indicó que es irreponsable que el presidente no tenga empatía con las personas que están muriendo en Ucrania.

El presidente Andrés Manuel López Obrador aseguró esta mañana que el acuerdo Glonass firmado con Rusia es como otros acuerdos firmados con diversos países y rechazó que tenga el propósito de espiar o afecte la soberanía.

The Global Positioning System or GPS has become entrenched in our daily life. Whether we want to maneuver traffic, or find a restaurant, it has made our life easier. But did you ever wonder who owns the GPS or who runs it? Originally Navstar GPS, the Global Positioning System is a satellite-based radionavigation system owned by the US government. And the United States Space Force operates it. India has found its homegrown alternative to the GPS in the form of NavIC. The government is taking rapid steps to enhance its adoption.  What is NavIC? NavIC stands for Navigation with Indian Constellation. It is an independent navigation satellite system developed by the Indian Space Research Organisation (ISRO). NavIC consists of eight satellites and covers the entire India. Additionally, it covers up to 1,500 km from its boundaries. When was NavIC started? NavIC was originally approved in 2006 with a $174 million budget. It was expected to be completed by late 2011. But it only became operational in 2018.   How is NavIC used? Currently, NavIC is being used to track public vehicles in India. It is also used to send emergency warning alerts to fishermen venturing into the sea where there is no terrestrial network connectivity. Also, it is being used for tracking and providing information in case of natural disasters. Off late, the Centre is pushing smartphone companies to adopt NavIC in India. NavIC vs GPS and others GPS provides global coverage but NavIC is currently limited to India and the adjacent areas. Three more navigational systems offer global coverage like the GPS. These are Galileo from the European Union, Russia-owned GLONASS and China's Beidou. Japan's QZSS provides navigational coverage of Asia-Pacific with a special focus on Japan. Why is the government vouching for NavIC? The government is aiming to remove foreign dependence on India's navigational requirements. It is more important in the case of strategic sectors. The centre believes that relying on GPS and others like it may not be wise for India as they are operated by defence agencies of their respective countries.

Vi lever i en värld som är fullkomligt besatt av att kunna bestämma sin position på en meter eller till och med en millimeter när. Därför har vi satellitnavigering. GPS, GLONASS, Galileo, vad de allt heter. Och de påverkar samhällets alla nivåer, från flygplanens navigering till banktjänsterna. Kriget i Europas hjärta kan påminna oss om hur sårbart det systemet är för den som vill oss illa. Redaktör: Marcus Rosenlund. E-post: kvanthopp@yle.fi

Het vrijwillige cyberleger van Oekraïne heeft de pijlen gericht op de treinsystemen in Belarus en op het Russische navigatiesysteem GLONASS, meldt persbureau Reuters.

Le « GPS », on connait ! En êtes-vous sûr ? Par abus de langage, « GPS » est le terme que l'on utilise pour définir l'ensemble des opérations de géolocalisation par satellite. En réalité, le « GPS » (pour Global Positioning System) est le système de positionnement américain. Bien d'autres existent encore : Glonass pour les russes, Beidou pour les chinois. Celui dont nous allons parler aujourd'hui est européen : la constellation Galileo. Plus d'infos sur le www.lacapsuledelespace.com

This week's EYE ON NPI knows where it's been and where its goin'! We reckon you'll love the ST Teseo-VIC3DA and Automotive GNSS Dead-Reckoning Module and Eval Kit (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/teseo-vic3da-automotive-gnss-dead-reckoning-module), a technology that improves on GPS/GNSS by adding an IMU and odometer to help determine location in places where GPS signal is unable to reach such as tunnels and canyons. We've covered GPS (https://en.wikipedia.org/wiki/Global_Positioning_System) modules before on EYE ON NPI - they're many-decades-old technology that uses a satellite constellation to calculate 3D location on Earth with ~10 meter precision. They're great for use with cars or trucks because GPS works anywhere on the planet, and when combined with digital maps can easily calculate instructions, arrival time and recommended routes. However, GPS has a few things that it can't do. Most important is it cannot work at all if there's no clear view of the sky. One needs to constantly be receiving GPS data from 3+ satellites in order to determine location. So, if you're in tunnel or in a city-made canyon (http://wikimapia.org/6909209/Canyon-of-Heroes), or if there's RF shielding or interference, you simply 'drop off' the planet. Super awkward! For those situations, some companies or technologies can take advantage of "WiFi Assisted GPS" (https://link.springer.com/chapter/10.1007/978-3-642-13618-4_14) this is where a secondary base station, or WiFi signal names, can be used to help locate during low-visibility. This works particularly well in cities, of course, where there's a high density of AP names that don't change. But it's still pretty useless in a tunnel or outside a city center. There's also RTK, (https://blog.adafruit.com/2020/06/08/eye-on-npi-u-blox-c099-f9p-application-board-for-zed-f9p-gnss-rtk-module-eyeonnpi-adafruit-digikey-digikey-ublox/) which is awesome for increased precision and accuracy - but that requires a base station within a couple-hundred meters, and another transmission link on every device, so while it's used for some agricultural robotics, it's not always possible to implement (but it is worth investigating if you can control the environment where you're using GNSS.) So, finally we come to dead-reckoning techniques(https://en.wikipedia.org/wiki/Dead_reckoning). These work in an intuitive way: if you know where you last were and you count the number of steps and direction which you're going, then in theory you should be able to determine your exact location. Now, historically this technique has been used with boats and planes and hiking - in fact you probably learned it in scout camp. (https://en.wikipedia.org/wiki/Dead_reckoning#/media/File:CYA_Coastal_Navigation_With_Dead_Reckoning_2.jpg) And, while in theory it should be a perfect way to determine location, the implementation makes a massive difference on how usable the end product is. A slight error in direction angle makes for more and more drift error in the final result - and as humans struggle to calculate direction, it's better than nothing but not necessarily trustworthy without having reference checkpoints on a map. For this module, ST has worked on how to make it easy as possible to implement dead reckoning into your robot, with all the fixin's. First up, you're getting multi-constellation support. So not only American GPS, but also Europe's Galileo, Russia's Glonass, Japan's QZSS, and China's BeiDou systems. So if you can't get data from one constellation, you can use another. Next up, there's an internal 6-DoF sensor that is used as a tilt-compensated compass that will determine direction precisely. (GPS modules do give 'heading' but its just based on the last few locations). Next you need to calculate 'steps' - that's done with an odometer input. That pin is connected to a simple rotation-count sensor and direction sensor that will let the chip know how many ticks have passed since the last known fix. You can also send the odometer data over NMEA commands, btw. Finally, the module can combine this in the TESEO firmware to give you a fast (30 Hz) updated location! Usually this calculation stuff is the hardest part of doing dead reckoning so its really cool to see this all in one ST makes a very snazzy EVB-VIC3DA dev kit in an aluminum box and everything, (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) with ports and power supplies and LEDs so you can immediately toss it into your robot without any soldering or board layout required. The ST Dead-Reckoning GNSS modules TESEO-VIC3D (https://www.digikey.com/en/products/detail/stmicroelectronics/TESEO-VIC3DA/15276424), and EVB-VIC3DA eval boards (https://www.digikey.com/en/products/detail/stmicroelectronics/EVB-VIC3DA/15276423) are in stock right now, for immediate shipment from Digi-Key! Order today and I reckon' you'll be adding this great locating hardware to your design tomorrow afternoon.

In 1977 or thereabouts a collection of scientists huddled around a secret radio receiver in the US desert. This was the start of GPS, Glonass, Gallileo and the whole navigation industry. A GPS chipset now costs, in bulk, a few dollars so your watch, your phone, your computer all have GPS receivers and everyone knows where they are all the time. But how does this technology work? And are there situations when it does not work?A lecture by Richard HarveyThe transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/gpsGresham College has been giving free public lectures since 1597.

In June 2020, the 55th and final satellite in the Beidou constellation was successfully launched into geosynchronous orbit. The system provides global coverage for timing and navigation and offers an alternative to GPS, GLONASS and the Galileo positioning system. It has both civilian and military applications.

For decades, the US held a monopoly on the usage of The Global Positioning System (GPS), the satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems that provides geolocation and time information to a receiver anywhere on or near the Earth.But that monopolistic hold on navigational satellites is quickly loosening due to the new kids on the block. The EU's "Galileo", Russia's "GLONASS", and the bad boy of the trio--China's "BeiDou" (or "BDubs" as we dub it).These new satellites will provide service for telecom companies all over the world and in turn to potentially billions of users.

Galileo, BeiDou, Gps, Glonass: anche se non sono noti a tutti, questi nomi fanno ormai parte della nostra vita. Si tratta, infatti, dei sistemi di navigazione satellitare che offrono servizi di geolocalizzazione sempre più precisi, con una accuratezza al centimetro, in grado di rendere così più semplici e sicuri i trasporti. E non solo. Le novità e le evoluzioni di questo settore sono raccontate da Marco Lisi, consulente dell'Esa e della Commissione Ue, intervistato da Massimo De Donato, a Container, su Radio 24. Fra gli ultimi servizi lanciati dall'europeo Galileo, ad esempio, c'è Galileo Green Lane, un'applicazione nata durante il lockdown per ridurre il tempo di attesa dei mezzi pesanti lungo i corridoi TEN-T.

Avec son système de navigation Beidou, la Chine vient de montrer une fois de plus sa volonté de s’affirmer comme une grande puissance et surtout de démontrer sa capacité technologique à le faire. Quelles en sont les conséquences technologiques, commerciales et géopolitiques ? Pékin a lancé, cette semaine, le dernier satellite du système Beidou, un système de géolocalisation qui couvre désormais l’ensemble de la planète. Ce système s’ajoute aux projets européen Galileo, au russe Glonass, et évidemment au GPS américain. La Chine n’en a désormais plus besoin et n’est plus dépendante d’aucun autre système de navigation satellite. Nos Invités :- Jean-Yves Le Gall, président du CNES (Centre national d'études spatiales)- Isabelle Sourbès-Verger, chercheuse au CNRS Centre Alexandre Koyré, spécialiste des questions de géopolitique de l'espace et des politiques spatiales, auteure du livre « Un empire très céleste.

¿Dónde estamos? En estos momentos la pregunta parece simple de responder, gracias a los dispositivos móviles que reciben las señales de los satélites de los sistemas de posicionamiento como el GPS, GLONASS o Galileo. Pero el hecho de contar con una tecnología capaz de ofrecernos la información no significa que la respuesta a la pregunta sea fácil. Para llegar a este punto los seres humanos han tenido que adquirir un conocimiento muy exhaustivo de la forma de la Tierra y de sus movimientos, una información que ha sido posible gracias a una ciencia que recibe el nombre de Geodesia. La Geodesia tiene aplicaciones en la astronáutica, la navegación marítima, la observación y medición de los cambios a escala local o planetaria, la agricultura de precisión, etc. Para que nos lo explique estas cosas está hoy con nosotros Marcelino Valdés Perez de Vargas, geodesta del Instituto Geográfico Nacional.

Bonjour, je suis Laurent et je vous invite à embarquer dans le onzième épisode de Grand Largue, le podcast de la grande croisière et de la vie à bord d'un voilier. Cette cette semaine, après trois épisodes précédents qui étaient des entretiens avec des marins inspirants, et que je vous recommande d'aller écouter si vous ne l'avez pas déjà fait, on reviens à un format « solo » dans lequel je vais vous expliquer comment je fais pour naviguer en sécurité avec une tablette, sans cartes papier. Je sais que c'est un sujet, en particulier sur les réseaux sociaux français, qui fait polémique. Et que cette pratique est considérée par certains comme vulgaire, irresponsable, en un mot hérétique. Je sais que certaines école continuent à enseigner la navigation à l'ancienne, sur carte. Et je suis pour. Car cette méthode à l'ancienne a des vertus pédagogiques évidentes : en particulier celle de comprendre dans le détail ce que fait votre GPS automatiquement. Mais en navigation, il ne s'agit plus de faire de la pédagogie, il s'agit avant tout d'arriver à bon port. Et donc le GPS me semble la bonne solution. Mais attention, il ne s'agit pas d'une solution miracle. Il ne s'agit pas d'appuyer sur un bouton et d'attendre d'arriver à bon port. Ce phantasme n'existe pas et ceux qui pensent le contraire sont dans la parfaite configuration pour avoir de grosses déconvenues. Ce que je me propose de partager avec vous est ma solution pour tirer partie de toute la puissance du numérique en navigation, et ce , en toute sécurité. Avant d'aller dans le détail de cette méthode, je vais vous donner les trois raisons qui font qu'aujourd'hui le GPS est plus sûr que le papier. Et je terminerai par vous donner mes 5 critères pour un choix d'équipement. Comme toute activité sportive, la pratique de l'activité se fait sous la pleine et entière responsabilité du pratiquant.

In questa puntata intervisto Francesco Matteuzzi - SmartNet Product Manager per l'Italia presso Leica Geosystems - che ci parla della rete di stazioni GNSS permanenti Hexagon SmartNet.Per una misura satellitare di precisione è necessario conoscere la posizione di due ricevitori e misurare il vettore "base" ("baseline").Una rete di stazioni permanenti ti permette di sfruttare una serie di basi fisse, sul territorio nazionale, con cui comunicare per misurare la posizione del tuo rover in campo ed in tempo reale (RTK).La rete SmartNet - che forse conosci con il vecchio nome di "Italpos" - fa questo (e qualcosa in più) e Francesco ci spiega il suo funzionamento, la sua infrastruttura, le sue caratteristiche ed i suoi piani di abbonamento, il tutto condito con un po' di nozioni sul principio della misura satellitare.Questo è il portale italiano di riferimento per il servizio nazionale di Hexagon SmartNet: https://hxgnsmartnet.com/it-itScrivimi su Telegram: t.me/paolocorradeghiniIscriviti al canale Telegram di 3DMetrica: t.me/tredimetricaLeggi gli articoli ed iscriviti alla newslettere sul blog: www.3dmetrica.itDiventa un finanziatore e sostieni economicamente 3DMetrica su Patreon: www.patreon.com/3dmetricaIn questa puntata ho inserito queste musiche:"V" by Weary Eyes from Fugue;"Once the clouds lift" by Weary Eyes from Fugue;"Your battles are over" by Weary Eyes from Fugue.

In questa puntata ti parlo del tracciamento topografico, raccontandoti un'esperienza diretta fatta sul campo utilizzando un'antenna satellitare GNSS.Il tracciamento è l'operazione (o le operazioni) che ti permette di materializzare sul campo un punto (o, più frequentemente, più punti) di cui conosci le coordinate.Tracciamenti di precisione spinta (come quelli necessari per i plinti di fondazione di una struttura) richiedono strumenti di precisione adeguata (stazioni totali molto performanti), ma si può fare un tracciamento anche con un'antenna satelittare, se non hai necessità di accuratezze elevate.In questa puntata ti racconto un'esperienza di tracciamento per individuare la posizione di alcuni pozzi piezometrici in un'area industriale che sono stati coperti nel tempo.Scrivimi su Telegram: t.me/paolocorradeghiniIscriviti al canale Telegram di 3DMetrica: t.me/tredimetricaLeggi gli articoli ed iscriviti alla newslettere sul blog: www.3dmetrica.itDiventa un finanziatore e sostieni economicamente 3DMetrica su Patreon: www.patreon.com/3dmetricaIn questa puntata ho inserito queste musiche:"V" by Weary Eyes from Fugue;"Once the clouds lift" by Weary Eyes from Fugue;"Your battles are over" by Weary Eyes from Fugue.

Il post-processamento dei dati rilevati da un ricevitore satellitare può spaventare un pochino se lo paragoni all'immediatezza di un rilievo RTK, o nRTK, in cui vedi subito, sul controller e sul campo, le coordinate dei punti che stai rilevando.Ma il post-processing ti permette di avere molto più controllo sui dati acquisiti per raggiungere i migliori risultati possibili sulle coordinate dei punti battuti sul campo.Puoi escludere satelliti instabili, controllare le effemeridi, impostare diversi angoli di "cut off", e gestire un sacco di parametri per tirare fuori dati robusti e affidabili.Tiziano Cosso ci parla ancora di GNSS e di accorgimenti da prendere sul campo durante un rilievo che sarà trattato successivamente in ufficio e ci racconta anche di quello che succede un volta scaricati i dati.Qui trovi due link a cui accedere per prodotti utili al post processing GNSS e, in particolare, per le effemeridi precise, rapide e ultrarapide:ftp://cddis.gsfc.nasa.gov/gps/products/ftp://igs.ensg.ign.fr/pub/igs/products/Invece trovi TIziano qui:http://www.gter.it/https://www.linkedin.com/in/tiziano-cosso-891a6837/

Il rilievo GNSS in modalità RTK ha bisogno di alcuni accorgimenti da prendere in campo per avere dati validi, robusti e affidabili.In questa puntata Tiziano Cosso continua a parlarci di rilievo satellitare con un focus specifico sull'acquisizione RTK.Si parla di multipath, angolo di cut off, D.O.P., Baseline, Latenza...Tutti aspetti importanti che, se conosciuti e controllati, contribuiscono a dare confidenza all'operatore in fase di rilievo e solidità ai dati rilevati.Trovi informazioni e contatti su Tiziano qui:http://www.gter.ithttps://www.linkedin.com/in/tiziano-cosso-891a6837/

Il rilievo satellitare di precisione lo puoi fare usando la tua antenna in modalità RTK oppure facendo un posizionamento statico e post processando i dati in ufficio.In questa puntata, Tiziano Cosso di GTER s.r.l., ci racconta le differenze tra un metodo e l'altro ed i pregi di ciascuno di essi.Questa è la prima puntata di una serie che faremo, sempre insieme a Tiziano, specificatamente sul rilievo satellitare, di cui lui è un grande esperto.Trovi i contatti di Tiziano Cosso qui: www.gter.it

新知日历 | 喜马拉雅平台首档自制知识资讯类音频节目从专业人士演讲、权威学术期刊、社会热点文章，行业大数据平台，分析报告等各类来源提取新认知、新观点和新趋势，为用户提供每日高品质知识资讯。新知识 | 点一次外卖，你调动了几颗卫星？点外卖已经成为了现代人的一种习惯。 为了“吃”其然“吃”其所以然，我来考考你啊： 外卖员是怎么在短短几十分钟内完成找饭店-找路-找你这一流程的？ 没错，答案就是手机导航。 其实啊，手机导航背后还有个“大靠山”，那就是天上的卫星。这就厉害了，那我们点一次外卖，需要动用几颗卫星呢？ 答案是4颗。大部分手机导航软件采用了GPS系统，这个系统一共部署了31颗卫星，覆盖了地球表面超过98%的范围。 这样的部署保证了在地球上任意一点都能够同时被其中4颗卫星捕捉到。这4颗卫星就像一个广播台，24小时对外广播自己的位置和时间。外卖员手机内置的导航芯片同时接收到这4颗导航卫星发布的信息后，迅速可以列出一个方程组：解出饭店和你家所在位置的经度、维度、高程和时间这4个未知数，然后规划出最佳路线。不过，世界这么大，外卖员会不会找错地方呢？这你就多虑了，官方数据显示，民用GPS的定位精度在5米以内，军用、航天、商用领域的定位精度可以达到厘米级，甚至毫米级！ 有了导航这个超级外挂，美味佳肴当然能热气腾腾的送到你手上啦！ 导航系统不光能帮助外卖员快速送餐，还能方便我们的出行。 无论是开车、骑车还是步行，导航都能规划出最短、最快或者红绿灯最少的路线，简直是路痴之宝。从此，妈妈再也不用担心我迷路了。 不过，这样一个伟大的系统当初可不是为了帮助懒人、拯救路痴而设计的。 从上世纪70年代开始，美军为了实时掌握“我在哪”“我的队友在哪”“敌人在哪”这些重要信息，一口气发射了24颗卫星，建成了“全球卫星定位系统”。也就是GPS，全称是Global Positioning System。 有了GPS这项黑科技的加持，在海湾战争中，美军的导弹和战斗机基本实现了“指哪打哪”的高精度准确打击。秒杀了敌方在人员和武器数量上的优势，以很小的伤亡代价打了胜仗。 这就好比，打败康师傅的不是五谷道场，而是美团外卖。 吃了大亏以后，许多国家才恍然大悟：“原来打仗还能这么玩！” 于是大家争先恐后地建立自己的导航系统，与GPS分庭抗礼。 目前，世界上一共有4个全球卫星导航系统，分别是美国的GPS系统、欧洲的伽利略系统（Galileo）、中国的北斗系统和俄罗斯格的洛纳斯系统（GLONASS）。它们一起被联合国卫星导航委员会认定为“全球卫星导航系统四大核心供应商”。 在民用市场份额上，GPS最大，伽利略系统次之，北斗第三，格洛纳斯第四。除此之外，还有两个区域卫星导航系统：日本“准天顶”系统和印度区域导航卫星系统（IRNSS）。 虽然目前美国的GPS系统占绝对优势，但现在很多手机也可以兼容北斗系统了。 比如小米8和华为手机的部分型号就采用了GPS+北斗的导航系统，这样的多系统组合有利于提升定位精度。 换句话说，作为使用者，卫星系统和卫星数量是越多越靠谱。所以说，GPS和北斗并不是对手关系，而是互相扶持、彼此成就。 是不是多了些惺惺相惜的意味呢？ 既然导航如此靠谱，怎么有时还会听到“导航失灵”的抱怨呢？ 从理论上讲，有些极端情况可能会降低导航信号强度。比如太阳黑子爆发，由此产生的电磁波、X射线和强紫外线等能够影响地球大气层中的电离层。 但雨雪、云层、气压、雾霾等常见因素都不会影响导航卫星的定位功能。如果你觉得导航失灵了，多半是接收端，也就是手机或者车载导航的问题。导航系统需要在开阔的地方使用，地下停车场、隧道、高架桥、密林小路和高楼林立的窄道等地段会导致信号衰减。 另外，观察一下手机周围是不是放置了强磁场物品、是不是有隔热纸或者金属成分遮蔽。同时检查导航软件是否更新了最新地图包，这些都是可能导致定位不准的原因。 所以，下次导航出问题，可别把锅甩给导航卫星了，多从自身找找原因。 除了帮外卖员送货和给路痴指路以外，卫星还是一位全能型选手。在预防森林火灾、监测云层移动、定位高产渔场等方面都身手不凡。 有兴趣的话，去探索一下吧！ 以上就是今天的新知日历。 关于导航，你有什么故事想要分享或者吐槽吗？欢迎在评论区给我留言。 我是煜霖，下期再见。Source1、北斗有35颗卫星，而GPS有24颗卫星，为什么二者数量不同？ 2、GPS定位为什么要最少4颗卫星？3、全球卫星导航哪家强？撰稿 | 董璞玉主持人 | 张煜霖，原海南电视台、杭州电视台主持人、记者。主编 | 韩悦思节目运营 | 柳婷婷专辑图视觉创意 | 贺归昀主视觉 | 李芳舟

Marine Automated Identification System (AIS ) is explained by Doug in this interview. He talks about how it may help you be safer in your offshore boating. AIS is a real time mesh network technology which provides constantly updated data on the identity and movement of vessels and other marine objects. The AIS device uses positioning technologies such as GPS, GLONASS or COMPASS to calculate dynamic data on the position and movement of the vessel, which is instantly fused with static data identifying the vessel on which it is located. This information is broadcast on defined radio frequencies whilst simultaneously receiving similar messages from other AIS devices within range. This provides each AIS device with a constant feed of real time information on the surrounding marine domain.

Because of Geocaching... Yorkshire Yellow "Because of geocaching - I've been to some really great places I wouldn't have been to otherwise." Feedback... From Denise aka Ey Up Me Duck... Hi Mark, Sam and Sophie, I have finally got around to listening to your podcasts (although I have just noticed there is one more (the latest) for me to listen to). I have really enjoyed them. It felt just like I was sat in the room with you. I can't remember all the questions you have raised but here are our answers to the ones I can remember. GPS vs Phone - I'm with Sophie on this one as we tend to go out for the whole day and the battery on the phone runs out. We don't mind the phone for cache and dashes and also if there is a new one in the area and we can't be bothered to mess about putting it on the GPS but generally we prefer the GPS and if are in another country then we don't have roaming charges - though this nearly backfired on us last year when we went to Cyprus because although we knew we had loaded 500 plus caches onto the GPS when we powered it up in our villa it only showed 10!!!! We were devastated. Luckily  Philip (brother) was due out two days later so he brought the laptop out and saved the day! Caching and holidays - we now tend to plan holidays in places where we can cache too. New Year Caching Resolutions: well last year we had found just over 200 caches and I said to the Old Soldier that I'd like to get to 500 by the end of the year ... we are now almost at the 2000 mark!!!! So this year our aim is get 2000 caches, get over 100 on a day, cache in at least one more country and cache in at least 5 more counties and complete 2 challenge caches. Urban Vs Rural - we enjoy both. If we have a lot of time (or if we are with the Scouts and want to wear them out so they sleep at night) we tend to do countryside walks. But sometimes we only have a few hours spare and so then we do ones we can park near. It also depends on the weather. It is not nice caching in the pouring rain so wouldn't plan to do a walk but might do a few round town. We also prefer trails where we can cycle around due to the Old Soldiers injuries. Most important piece of equipment (apart from GPS and resources). The Old Soldier says tweezers and I say my extending torch / magnet thing. I think that I have mentioned most of the shows you have done - keep up the good work. News & Events...

With residual uncertainties at the 10^-18 level, modern atomic frequency standards constitute extremely precise measurement devices. Besides frequency and time metrology, they provide valuable tools to investigate the validity of Einstein's theory of general relativity, to test a possible time variation of the fundamental constants, and to verify predictions of quantum electrodynamics. Furthermore, applications as diverse as geodesy, satellite navigation, and very long base-line interferometry may benefit from steadily improving precision of both microwave and optical atomic clocks. Clocks ticking at optical frequencies slice time into much finer intervals than microwave clocks and thus provide increased stability. It is expected that this will result in a redefinition of the second in the International System of Units (SI). However, any frequency measurement is based on a comparison to a second, ideally more precise frequency. A single clock, as highly developed as it may be, is useless if it is not accessible for applications. Unfortunately, the most precise optical clocks or frequency standards can not be readily transported. Hence, in order to link the increasing number of world-wide precision laboratories engaged in state-of-the-art optical frequency standards, a suitable infrastructure is of crucial importance. Today, the stabilities of current satellite based dissemination techniques using global satellite navigation systems (such as GPS, GLONASS) or two way satellite time and frequency transfer reach an uncertainty level of 10^-15 after one day of comparison . While this is sufficient for the comparison of most microwave clock systems, the exploitation of the full potential of optical clocks requires more advanced techniques. This work demonstrates that the transmission of an optical carrier phase via telecommunication fiber links can provide a highly accurate means for clock comparisons reaching continental scales: Two 920 km long fibers are used to connect MPQ (Max-Planck- Institut für Quantenoptik, Garching, Germany) and PTB (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany) separated by a geographical distance of 600 km. The fibers run in a cable duct next to a gas pipeline and are actively compensated for fluctuations of their optical path length that lead to frequency offsets via the Doppler effect. Together with specially designed and remotely controllable in-line amplication this enables the transfer of an ultra-stable optical signal across a large part of Germany with a stability of 5 x 10^-15 after one second, reaching 10^-18 after less than 1000 seconds of integration time. Any frequency deviation induced by the transmission can be constrained to be smaller than 4 x 10^-19. As a first application, the fiber link was used to measure the 1S-2S two photon transition frequency in atomic hydrogen at MPQ referenced to PTB's primary Cs-fountain clock (CSF1). Hydrogen allows for precise theoretical analysis and the named transition possesses a narrow natural line width of 1.3 Hz. Hence, this experiment constitutes a very accurate test bed for quantum electrodynamics and has been performed at MPQ with ever increasing accuracy. The latest measurement has reached a level of precision at which satellite-based referencing to a remote primary clock is limiting the experiment. Using the fiber link, a frequency measurement can be carried out directly since the transmission via the optical carrier phase provides orders of magnitude better stability than state-of-the-art microwave clocks. The achieved results demonstrate that high-precision optical frequency dissemination via optical fibers can be employed in real world applications. Embedded in an existing telecommunication network and passing several urban agglomerations the fiber link now permanently connects MPQ and PTB and is operated routinely. It represents far more than a proof-of-principle experiment conducted under optimized laboratory conditions. Rather it constitutes a solution for the topical issue of remote optical clock comparison. This opens a variety of applications in fundamental physics such as tests of general and special relativity as well as quantum electrodynamics. Beyond that, such a link will enable clock-based, relativistic geodesy at the sub-decimeter level. Further applications in navigation, geology, dynamic ocean topography and seismology are currently being discussed. In the future, this link will serve as a backbone of a Europe-wide optical frequency dissemination network.
