Iridium Communications Inc. confirmed commercial availability of its Iridium PNT ASIC on 14 July 2026, delivering the first-to-market chip engineered for hardware-level GNSS jamming and spoofing protection in aviation avionics and autonomous systems[1]. The 8mm x 8mm application-specific integrated circuit provides cryptographically secure timing and location data via one-way satellite bursts, operating reliably inside structures and contested environments where traditional GNSS fails[1][7]. Over 150 organizations across aviation, maritime, and critical infrastructure sectors have requested integration since the October 2025 unveiling, signaling urgent sector demand for assured positioning, navigation, and timing integrity[1]. The ASIC enables device manufacturers to embed anti-jamming capabilities directly into hardware, addressing escalating threats to GPS-dependent operations without requiring new ground infrastructure[1][4].
