PNT Podcast

An interview with Ernest Wong, the PNT Technical Lead at The Department of Homeland Security Science and Technology Directorate.  We discuss viewing PNT as a Cybersecurity Issue, the PNT Conformance Framework, and how Zero Trust Architecture principles apply to PNT. The resources Ernest mentions on this episode are available at: https://www.dhs.gov/science-and-technology/pnt-program 

A brief synopsis of why PNT is important, why it's been overlooked, and what you can do about it.

Traceable Time as a Service delivers accurate, traceable time over a secure VPN connection to provide a traceable time reference for your network.

Cybersecurity is a hot topic today. Hackers are always looking to undermine our network connections and we are always trying to protect against them. What role does PNT play?

Time synchronization is the ability for all clocks to have the same time. But what time is it? If your time synchronization deployment uses time from the internet, your organization may be at risk.

GPS and other GNSS operating in Medium Earth Orbit (MEO) are the primary domain for Positioning, Navigation and Timing (PNT) services. But these signals are weak and subject to interference, both intentional and unintentional.

Positioning, navigation and timing (PNT) solutions are at the heart of critical military operations, powering everything from precision missile defense systems and warfighter navigation to Intelligence, Surveillance and Reconnaissance (ISR) data management.

Keeping accurate time is fundamental to many cybersecurity applications. We summarize a few best practices to reduce the risk of attack.

A recent decision will keep the leap second around until at least 2023. Understand the leap second vulnerability and plan ahead for the next leap second so that your applications will continue to operate smoothly.

The federal fiscal year end is fast approaching, and 2021 may see an increase in end of year funds due to COVID-related procurement delays. As you explore the best use of year end funds, here are the top Resilient Positioning, Navigation and Timing (PNT) applications government program managers and systems integrators invest in for improved performance, security and mission success.

Global Navigation Satellite Systems (GNSS), particularly the US Global Positioning System (GPS), are an ever-present feature of modern life. However, they provide much more than simply the positional information that most people associate them with, and which anyone with a GPS-enabled smartphone is aware of.

(And Which One Do You Really Need?) NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The procedure used by the Time Server to assemble and send out a time stamp is exactly the same whether NTP (i.e., full implementation NTP) is used, or SNTP is used.
