A stabilization system for space platforms, satellites and the like. One arrangement for demonstration purposes incorporates a frame and a pair of motor/flywheel units which are pivotably mounted to the frame. These units are retained in positions of alignment with the frame axis and energized briefly to develop a torque for rotating the frame. Retraction of a retaining pin permits the units to pivot by 90 degrees, immediately generating precession forces which abruptly stop the frame at the desired angular orientation.
