Iridium Begins GNSS Anti-jamming/spoofing Chip Sales
Avionics manufacturers can integrate chip to prevent GNSS compromising

Satcom provider Iridium Communications is now making its satellite-based positioning, navigation, and timing (PNT) application-specific integrated circuit (ASIC) commercially available, following the announcement of development nine months ago. The PNT chip is available to developers of navigation products for protection from global navigation satellite system (GNSS) jamming and spoofing, which affects the relatively weak signals from GNSS constellations.

The ASIC “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,” according to Iridium. The chip measures 8 by 8 mm and weighs less than 0.2 grams.
