Abstract
For a spacecraft in an equatorial or low inclination orbit predictable roll disturbance torques due principally to solar radiation pressure are minimized by interacting a magnetic dipole oriented parallel to the spacecraft's yaw axis with the earth's magnetic field. Signals either from an on board sun sensor or from an earth station are utilized by the satellite mounted magnetic switching and driver circuit to control the compensating torques.
