  • Telecommunications satellite architecture
    Patent number: 10207825
    Abstract: A telecommunications satellite stabilized on three axes includes a set of dissipative equipment constituting a payload of the satellite. The satellite includes support data transmission antennas and is substantially parallelepipedal in shape with the panels forming two opposite faces, east and west faces. The panels form two additional opposite faces, north and south faces, and include radiator surfaces on their external faces. The radiator surfaces are configured to cool the electronic equipment of the satellite. The equipment installed on the north and south panels dissipate thermal power corresponding to less than 25% of the total dissipated power.
    Type: Grant
    Filed: December 24, 2014
    Date of Patent: February 19, 2019
    Assignees: AIRBUS DEFENCE AND SPACE SAS, THALES, CENTRE NATIONAL D'ETUDES SPATIALES CNES

  • Method for stationing a satellite and in-orbit testing of its payload
    Patent number: 10005567
    Abstract: A method for stationing a satellite comprises a transfer phase, during which the satellite moves on an elliptical geosynchronous orbit, the orbit being deformed progressively by application of a thrust by electrical or hybrid electrical-chemical propulsion to bring it closer to a geostationary orbit. The transfer step comprises a substep during which, during a plurality of revolutions of the satellite, the thrust is stopped for a fraction of orbital period and tests of a telecommunications payload of the satellite are performed in the absence of thrust.
