Abstract
Orientation system and process of an artificial satellite in low orbit. Aerodynamic control surfaces producing rotations of the satellite by upper-layer atmosphere are combined along two axes to magnetic couplers ( ) producing rotating movements along the three principal axes of pitch, roll and yaw thanks to the Earth's magnetic field. Great precision may be obtained in orienting the satellite without substantial energy consumption. Command laws are provided.
