Iridium Communications Inc. (Nasdaq: IRDM) announced the commercial availability of its Iridium PNT ASIC, a chip designed to protect GPS- and GNSS-dependent devices from jamming, spoofing, and other signal interference threats.

First unveiled in October 2025, the application-specific integrated circuit measures 8 by 8 millimeters and weighs less than 0.2 grams. The chip delivers cryptographically secure timing and location data through one-way signal bursts from the Iridium satellite network, including inside structures and in contested environments.

Since its unveiling, Iridium said it has received interest from more than 150 organizations across maritime, unmanned and autonomous systems, aviation, telecommunications, and critical infrastructure sectors.

Two companies have announced plans to integrate the chip. Solace Communications is incorporating the ASIC into its Vector family of assured PNT products, which combines Iridium PNT with multi-band GNSS and inertial sensing. Skyband Systems will integrate the chip into its M100 LRU navigation unit for business and commercial aviation, designed to alert crews to GNSS jamming and spoofing.

According to a 2019 study sponsored by the U.S. National Institute of Standards and Technology, a GPS outage was estimated to cost the U.S. economy approximately $1 billion per day, a figure Iridium states would exceed $1.3 billion per day adjusted for 2026 inflation levels.

"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 of PNT at Iridium.

The chip is intended for use in financial markets, telecommunications networks, power grids, and government systems that rely on precise time synchronization. Iridium is headquartered in McLean, Virginia.
