The Federal Communications Commission (FCC) in the US has received a request from AST SpaceMobile to modify an existing license that would allow it to transmit within the amateur radio 70 cm band. Specifically, the company seeks the use of the 430-440 MHz spectrum to perform telemetry, tracking, and telecommand between ground stations and a constellation of 243 satellites in low-earth, non-geostationary orbit.
Based on activity within the AMSAT-DL forums, it’s been suggested that AST SpaceMobile has interfered with the 70 cm amateur bands in the past. Communications Daily reported in 2023 that Germany required AST SpaceMobile to shut off operations when in radio range of the country. The government cited non-compliance with ITU regulations.
AST SpaceMobile is building a satellite constellation based cellular network that can utilize existing smart phones. The company is based in Midland, Texas, US and is publicly traded.
