Abstract: The low earth orbit radar remote sensing or telecommunication satellite includes an antenna forming member in a plane passing through the center of Earth, for example, the plane of its orbit. The antenna(s) are on one or both faces of the member. The height of the antenna forming member is greater than its dimension in the direction of travel of the satellite, so that the satellite is naturally stabilized by the gravity gradient. The solar generator cells are carried by the antenna forming member on the face that is kept facing towards the Sun in the case of a 6 H/18 H local time heliosynchronous orbit. The antenna forming member comprising a plurality of hinged panels over which the received or transmitted wave phase control means are distributed, it includes a plurality of GPS sensors distributed over the panels, enabling measurement and subsequent compensation by the phase-shifters of deformations of the member.
