Abstract
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.
