Device for aligning the roll axis of a rotating artificial satellite having radial solar panels equipped with angularly movable control surfaces at their extremities. The device includes a motor associated with each control surface for controlling the angle of the control surface with respect to the solar panel, each motor being actuated by a current which is dependent on the displacement of the roll axis from a desired position and which varies cyclically during the rotation of the satellite. The motor also includes a detector for detecting the angular speed of movement of the control surface and introducing a damping effect.

A device for controlling the roll axis of a rotating artificial satellite relative to the sun within an angle of 60°, said satellite having a plurality of radial solar panels, at least some of which are provided at their outer extremities with angularly movable control surfaces responsive to solar pressure, said device comprising: an electromagnetic motor associated with each of said control surfaces for controlling its angular position relative to its associated solar panel; means including detecting, filtering, control logic, and amplifying means for generating and supplying to said motors cyclic actuating currents dependent on errors of position or angular velocity of said satellite, whereby each said motor causes its associated control surface to vary its angular position during rotation of said satellite in a direction to reduce said errors; and detecting means associated with each motor for detecting the angular speed of the associated control surface and introducing a damping in the control of said surface.
