Abstract: Attitude maneuver control of high-earth-orbit satellite at roll and yaw axes with magnetically suspended gimbaling flywheel(MSGFW) is presented. The dynamic equations of satellite with MSGFW as actuator are developed. The control torque generates in roll and yaw axis when the gamble angles of flywheel change. Double MSGFWs mounted on the satellite with opposite rotation direction comprise the double MSGFWs attitude control system. The attitude control system works at zero momentum mode. Simulation results show that the satellite achieves attitude angle maneuver of 5° in 20 s with the gimbal angle of 3°. When the gimbal angle is 6° the satellite can achieve attitude angle maneuver of 12°. The future application of MSGFW on low-orbiting satellite is analyzed and the new concept in rapid maneuver and stabilization of satellite attitude control is proposed.

Key words: attitude dynamics, attitude maneuver, magnetically suspended gimbaling flywheel
