About: Inmarsat-6 F1

Inmarsat-6 F1 is a communications satellite to be operated by the British satellite operator Inmarsat and designed and manufactured by Airbus Defence and Space on the Eurostar 3000EOR satellite bus. Part of the Inmarsat-6 satellite fleet, it will be Inmarsat's first dual-payload satellite, with capabilities in both L-band (ELERA) and Ka-band (Global Xpress). Claimed to be the largest and most sophisticated commercial telecommunications satellite ever launched, as the first of two such vehicles, it was placed into supersynchronous transfer orbit on 22 December 2021. The onboard Fakel SPT-140D electric propulsion will then raise the satellite into final geosynchronous orbit.
