Iridium announces Iridium PNT ASIC for GNSS protection
Iridium has announced the commercial availability of the Iridium PNT ASIC, a first-to-market chip designed to help protect GPS- and GNSS-dependent devices from jamming, spoofing, and other growing threats.
Measuring just 8 by 8 millimetres and weighing less than 0.2 grams, the ASIC represents a major step forward in expanding access to assured PNT technologies at scale. The chip delivers cryptographically secure timing and location data from the Iridium satellite network through one-way signal bursts that are powerful enough to work where traditional GNSS often cannot, including inside structures and in contested environments.
By continuously validating signal integrity and delivering trusted PNT data anywhere on Earth, the Iridium PNT ASIC provides a new foundation not only for resilient navigation, but also timing. Financial markets, telecommunications networks, power grids, and governments all depend on precise time synchronisation to coordinate operations and maintain reliable service.
