Since the Iridium PNT ASIC's unveiling in October 2025, Iridium has received unprecedented demand from more than 150 organizations worldwide, spanning maritime, unmanned and autonomous systems (UXV), aviation, telecommunications, and other critical infrastructure sectors.

"The market response to the Iridium PNT ASIC has reinforced what we're hearing from customers around the world: assured PNT is becoming an essential capability across critical industries," said Dr. Michael O'Connor, executive vice president, PNT, Iridium. "With commercial availability, we're enabling manufacturers to integrate trusted timing and location capabilities into smaller, more efficient designs, making assured PNT accessible to more applications than ever before."

Measuring just 8 by 8 millimeters and weighing less than 0.2 grams, the application-specific integrated circuit (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 powerful new foundation not only for resilient navigation, but also timing. Financial markets, telecommunications networks, power grids, and governments all depend on precise time synchronization to coordinate operations and maintain reliable service.

As global reliance on GNSS continues to grow, so does the frequency and sophistication of signal interference such as jamming and spoofing. Recent incidents including the May 2026 in-flight jamming of United Kingdom Defence Secretary John Healey highlight increasing operational and safety risks associated with GNSS spoofing and jamming across commercial transportation, aviation, and critical infrastructure environments. According to a 2019 study sponsored by the U.S. National Institute of Standards and Technology (NIST), a GPS outage was estimated to cost the U.S. economy approximately $1 billion per day. Adjusted for inflation, that figure would exceed $1.3 billion per day in 2026, underscoring the growing importance of reliable backup solutions.
