Iridium has launched a new positioning, navigation, and timing (PNT) chip to protect satellite-dependent hardware from jamming and spoofing.
Since its initial preview in October 2025, the company says it has received interest from more than 150 organisations across the maritime, unmanned vehicle, aviation, and telecommunications sectors.
The application-specific integrated circuit (ASIC) measures eight by eight millimetres, weighs less than 0.2 grams, and delivers cryptographically secure timing and location data via the Iridium satellite network. The signal bursts are designed to operate inside structures and in environments where standard Global Navigation Satellite Systems (GNSS) are often blocked.
“With commercial availability, we are enabling manufacturers to integrate trusted timing and location capabilities into smaller, more efficient designs, making assured PNT accessible to more applications than ever before,” said Dr Michael O’Connor, Executive Vice President of PNT at Iridium.
Solace Communications will be one of the first partners to integrate the chip, utilising it in its Vector range of resilient PNT hardware.
The hardware combines Iridium PNT with multi-band GNSS, inertial sensing, LTE, and Iridium Short Burst Data (SBD) to provide telemetry, secure messaging, and continuous confidence scoring.
“Future navigation systems must do more than report a position,” said Adam Elcock, Co-Founder of Solace Communications.
“They must continuously determine whether that position and its timing can be trusted. That is the role Vector has been designed to fulfil and is now being deployed.”
