Iridium Communications Inc. has unveiled a dedicated, miniature application-specific integrated circuit (ASIC), the Iridium PNT ASIC. Engineered for seamless integration into a wide range of electronic devices, the Iridium PNT ASIC will deliver authenticated, pole-to-pole positioning, navigation and timing (PNT) data. It will provide a resilient alternative to traditional GNSS, offering protection against spoofing and jamming for consumer, industrial and government applications.
The Iridium PNT ASIC measures 8 x 8 mm and can be fit into devices ranging in size from consumer products to major infrastructure systems like power grids, transportation systems and telecom networks. When embedded in a device, the Iridium PNT ASIC receives a cryptographically secure time and location data signal from the Iridium satellite network that is 1,000 times more powerful than GPS and capable of working inside buildings. This can help GNSS-dependent applications to not only detect a problem but also maintain operations until it is resolved. The Iridium PNT ASIC will also continuously verify signal integrity, making it a suiitable alternative or primary source of PNT data.
Iridium showcased the ASIC’s capabilities during September’s Jammertest, an annual event that evaluates the resilience of GNSS and alternative PNT technologies under jamming and spoofing attacks. The Iridium PNT ASIC maintained both timing accuracy and reliable navigation during controlled exercises.
Iridium is inviting organizations to apply to participate in beta trials, and, if selected, they will receive Iridium PNT ASIC evaluation kits, enabling early integration and testing. The Iridium PNT ASIC is planned for commercial availability in mid-2026.
Iridium is highlighting the Iridium PNT ASIC at the International Timing and Sync Forum (ITSF) Oct. 27-30 in Prague.
