Learn more about about Resilient PNT, how it applies to defense and what current solutions exist to ensure the integrity of and access to PNT data.

In 2013, the Federal Communications Commission fined a person almost $32k for using a device intended to evade the fleet management tracking system on his company vehicle. The device in question: a GPS jammer.

Cybersecurity is a popular topic in the news today, but Position, Navigation, and Timing (PNT) security does not get the same attention. But like cyberattacks, attacks against GPS or other global navigation satellite system (GNSS) systems can have profound and damaging effects on critical infrastructure, financial institutions, and military capabilities.

Today’s critical infrastructure, including many military systems, rely on GPS for position, navigation and timing (PNT) reference. But what happens when GPS is lost or corrupted? How can alternative PNT signals support critical capability in this situation?

For military personnel, keeping sight of the enemy can mean the difference between life and death. Military leaders frequently emphasize their need for reliable and accurate positioning, navigation and timing (PNT) systems. Accurate PNT is critical for their communications, sensors, network systems, and search and rescue missions.

The increasing reliance on GNSS signals for positioning, navigation and timing applications across different industries has raised questions about GNSS vulnerabilities and how to address them. We sat down with John Fischer, Spectracom’s chief technology officer, to talk to him about Resilient PNT (also known as Assured PNT and Alternative PNT) and its implications for today’s GPS/GNSS systems.  This continues from Part 1 of John Fischer's Resilient PNT FAQ.

If you have critical infrastructure that demands the highest level of protection, you’re a candidate for an STL-based system.

By Lisa Perdue, Product Manager
 

STL is a new satellite-based GNSS augmentation system: Originating from the Iridium® constellation of 66 low-earth-orbiting satellites, STL is 1,000 times stronger than GPS/GNSS, reaching deep into buildings and preventing GPS/GNSS jamming without the aid of local infrastructure. STL signals are further protected by cryptographic security features that are much more difficult to misdirect or “spoof.”
