Iridium Communications Inc. has announced a miniature, application-specific integrated circuit, the Iridium PNT ASIC, designed to safeguard a wide range of global navigation satellite system (GNSS) devices from jamming, spoofing, and timing disruptions. The ASIC is intended for integration into consumer, industrial, and government equipment, delivering pole-to-pole authenticated positioning, navigation, and timing (PNT) data from the Iridium satellite network.

Recent incidents exemplify the growing threat to GNSS reliability, such as the September 2025 jamming of navigation aboard the European Commission president's aircraft and maritime GPS failures near Qatar in October 2025. According to a September 2024 OPSGROUP report, GPS spoofing now affects an average of 1,500 flights daily, marki
