Iridium has launched a global positioning and timing chip measuring 8mm by 8mm that is designed to protect GPS and GNSS-reliant systems from interference, spoofing, and signal loss.
The Iridium PNT ASIC (application-specific integrated circuit) system offers authenticated positioning, navigation, and timing data by connecting directly to the Iridium satellite network.
The chip was successfully tested during this year’s Jammertest event, where it maintained accurate timing and navigation under simulated jamming and spoofing conditions by leveraging Iridium’s satellite network, which transmits signals up to 1,000 times stronger than GPS.
“The market for alternative PNT solutions is shifting rapidly toward compact, integrated technologies,” said Mike O’Connor, Executive Vice President, PNT, Iridium.
“While Iridium PNT is already available in some systems, the Iridium PNT ASIC will take it to the next level to deliver the only truly global alternative to GPS in the smallest form factor available.”
“Whether in government, enterprise, or consumer applications, every device that relies on GNSS needs a dependable backup or reliable primary service in the event of disruption. The Iridium PNT ASIC delivers that dependability in a compact, all-in-one chip.”
The Iridium PNT ASIC is now available for beta testing, with commercial release planned for mid-2026.
