Iridium Launches PNT ASIC Amid Rising GNSS Jamming Threats

Iridium Communications has launched the Iridium PNT ASIC, a chip designed to protect GPS and GNSS-dependent devices from jamming and spoofing. This ultra-compact 8x8 mm chip weighs less than 0.2 grams and delivers secure timing and location data via the Iridium satellite network. Over 150 organizations across various sectors, including maritime and aviation, have shown demand for this technology since its unveiling in October 2025. The chip's capabilities are particularly relevant as recent incidents have highlighted vulnerabilities in GNSS systems, including a jamming event involving an RAF jet near the Russian border. The Iridium PNT ASIC aims to enhance resilience in critical infrastructure against such threats. Partners like Solace Communications and Skyband Systems are integrating the chip into their products to provide assured positioning and timing solutions.

Key Points: • Iridium's PNT ASIC is designed to combat GPS jamming and spoofing threats. • Over 150 organizations have expressed demand for the new chip since its unveiling. • Recent incidents, including a jamming event involving an RAF jet, underscore the need for resilient GNSS solutions.
