ABSTRACT:
The attitude of a spinning spacecraft (20) whose spin axis is substantially in the plane of the orbit is controlled without the use of reaction control thrusters. A two-axis gimbal (24) on which a momentun wheel (26) is mounted is secured to a central body (21). Two actuators (40, 42) are used to selectively pivot the gimballed momentum wheel (26) about each gimbal axis (x, y) in order to apply a control moment to change the attitude state of the spacecraft (20).
