The geocentric attitude stabilization of an earth satellite is studied. TRHE SYSTEM CONSIDERED IN THIS REPORT UTILIZES DIFFERENTIAL GRAVITY TO CONTROL THE VEHICLES ORIENTATION AND GYROSCOPES TO PROVIDE VEHICLE DAMPING. Several different gyroscope configurations that provde indirect gyroscope damping about all three of the vehicle axes are presented. For each of these configura tions, the equations governing the dynamics of the system are systematically developed in terms of the attitude deviation angles and the parameters of the orbit. The expressions for the state deviation angles and the torque which must be supplied by gyroscope torquers are also obtained.
