1. A momentum control device for positioning a spacecraft comprising:a plurality of bodies, each operable to spin about separate axes, to produce a plurality of forces; a unitary structure; mounting members connected to each spinning body and the unitary structure to provide a unitary combination to receive the forces; an attachment device comprising a plurality of struts having a predetermined static stiffness and passive damping connected to the unitary combination and adapted to be connected to the spacecraft to attenuate noise transmission from the bodies to the spacecraft and transmit the forces to the craft; a plurality of sensors operable to produce force signals indicative of the forces in said struts; and a control system connected to receive the force signals to control the operation of the spinning bodies in controlling the attitude of the spacecraft.
