The invention relates to a telecommunications satellite (10), of the type which is stabilized on three axes, said satellite comprising a set of dissipative equipment, constituting the payload of the satellite, said satellite being of substantially parallelepipedal shape, the panels of which forming two opposite faces, termed East (16) and West (17), support data transmission antennas (19), and the panels forming two other opposite faces, termed North (14) and South (15), comprise on their external face radiator surfaces intended for cooling the electronic equipment of the satellite. The equipment installed on the North (14) and South (15) panels dissipate thermal power corresponding to less than 25% of the total power dissipated.

    L'invention vise un satellite (10) de télécommunications, de type stabilisé sur trois axes, ledit satellite comportant un ensemble d'équipements dissipatifs, constituant la charge utile du satellite, ledit satellite étant de forme sensiblement parallélépipédique dont les panneaux formant deux faces opposées, dites Est (16) et Ouest (17), supportent des antennes (19) d'émission de données, et les panneaux formant deux autres faces opposées, dites Nord (14) et Sud (15), comportent sur leur face externe des surfaces de radiateurs destinées au refroidissement des équipements électroniques du satellite, Les équipements installés sur les panneaux Nord (14) et Sud (15) dissipent une puissance thermique correspondant à moins de 25% de la puissance dissipée totale.
