Soldiers Test Newest Dismounted GPS Devices, Replacing DAGRs

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.

Washington View: Big Wheels Keep On Turning – Rolling On The River To 5G

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.

Italy and Qascom to Land First GNSS Receiver on the Moon

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.

Are Elliptical Galileo Satellites Usable for RTK?

Galileo satellites 5 and 6 (E18, E14) were declared unusable in February 2021 after reports indicating repeatable daily problems with RTK. This article explores the possible impact of deviant elliptical orbits on the performance of RTK and finds that there is no reason to expect any anomalies caused by high orbit eccentricity per se. Thus there is no reason to declare the satellites unhealthy.
