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.
