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.

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.”
