ABSTRACT:
A satellite adapted to be stabilized in terrestrial orbit by rotation about an axis oriented at least approximately NORTH-SOUTH has on its external wall a solar generator composed of a plurality of columns of solar cells divided into groups adapted to supply at least one given electrical voltage. In each of a plurality of groups equi-angularly distributed in the circumferential direction, the cells straddle two columns electrically connected by at least two electrical connections forming with the group(s) to which the connection belong an electrical loop. The clockwise or counterclockwise direction of current flow is the same for least the majority of the electrical loops and is so chosen that, at any time, the loops which are illuminated at this time by the Sun, by virtue of interaction with the terrestrial magnetic field, produce a compensating torque in the opposite direction to the solar radiation pressure torque.
