Iridium begins commercial sales of PNT ASIC chip to mitigate GNSS jamming and spoofing in aviation

Iridium has launched its PNT ASIC chip for commercial sale, targeting increasing GPS/GNSS jamming and spoofing threats. The chip is designed to provide backup positioning, navigation and timing (PNT) capabilities when GNSS signals are compromised, offering an additional layer of resiliency for aircraft avionics.

Briefing

What Hype is tracking

  • [Iridium’s PNT ASIC commercialization] signals a shift from relying solely on vulnerable GNSS signals to adding onboard backup PNT for operations degraded by jamming/spoofing.
  • The chip’s positioning/navigation/timing role directly affects avionics design choices and safety cases for aircraft operating in contested or interference-prone environments.
  • Treating GNSS spoofing/jamming as an operational security problem increases pressure on OEM and avionics suppliers to integrate complementary anti-compromise technologies, alongside broader [cybersecurity and resilience] measures.
