NextNav and Satelles, Inc. have partnered on an alternative positioning, navigation, and timing (PNT) testbed in the San Francisco Bay Area. Designed and managed by NextNav with a timing source from Satelles, the testbed creates scenarios and conditions to rigorously test the precision and resilience of alternative PNT solutions

The U.S. Army has put its replacement for the handheld Defense Advanced GPS Receiver (DAGR) under field testing in reconnaissance and fire missions in a variety of threat scenarios, to understand its performance in a realistic operational environment. The Dismounted Assured Positioning, Navigation, and Timing System (DAPS) could enable warfighters to better shoot, move and communicate in a GPS degraded environment.

Spirent Communications has launched GNSS Foresight, a cloud-based solution that empowers GNSS users with advance knowledge about the strength and reliability of GNSS signals in exact locations within their operational areas. The service will have early application for aviation, unmanned and autonomous platforms, but Spirent VP Jeremy Bennington told Inside GNSS that its potential is far wider.

Ligado Networks had an early-year win in the form of a Federal Communications Commission denial of the National Telecommunications and Information Administration Stay Petition involving Ligado’s license for a terrestrial service in the mobile satellite services L-band. The company continues to roll toward deployment of a nationwide 5G network. While filings trickle in from the private sector, the feds work quietly behind the scenes on Congressional due-outs. In short, wheels big and small keep churning down the river to 5G.

A 2023 lander in the moon’s Mare Crisium will carry the first GNSS receiver to that planet’s surface: the Navigation Early Investigation on Lunar surface (NEIL) receiver with software-defined radio (SDR) technology. The receiver will spring from agreements between the U.S. National Aeronautics and Space Administration (NASA), the Italian Space Agency (ASI) and the Italian firm Qascom srl.
