Zusammenfassung:The attitude of a spinning spacecraft whose spin axis is substantially in the plane of the orbit is controlled without the use of reaction control thrusters. A two-axis gimbal on which a momentum wheel is mounted is secured to a despun platform. The despun platform is in rotational communication with the central body. Two actuators are used to selectively pivot the gimbaled momentum wheel about each gimbal axis in order to apply a control moment to change the attitude of the spacecraft.
