CesiumAstro files for 737-satellite Synchronicity fleet
CesiumAstro
CesiumAstro asked the FCC to license its own 737-satellite Synchronicity constellation for reconfigurable connectivity.
what happened
CesiumAstro filed an application with the FCC on July 6 for a new non-geostationary satellite constellation called Synchronicity, per Via Satellite. The filing requests up to 737 satellites deployed in two tranches at roughly 1,200 km and 1,100 km altitude, operating in Ku-, Ka-, and V-band, with a requested license deadline of January 6, 2027. It is the company's first stated plan to operate its own constellation rather than only sell satellite hardware and components.
why it matters
CesiumAstro raised $270 million in a Series C round plus $200 million in Export-Import Bank financing earlier this year and has built its business selling phased-array and software-defined radio hardware to other operators; a constellation of its own would make it a direct NGSO competitor rather than just a supplier. The filing adds another entrant to an already crowded FCC docket of proposed US broadband constellations competing for spectrum and orbital slots.
