The potentials of a double gimballed momentum wheel as an actuator for attitude control are discussed with respect to the related subsystems. A comparison is made between possible attitude control systems (hybrid, active, semiactive systems) to obtain the conditions under which a double gimballed momentum wheel would be preferred. A justification of the double gimballed momentum wheel is given and the characteristics defining the wheel system, including factors such as angular momentum, rotor bearing, rotor speed, gimbal configuration and suspension, and actuators, are determined. They can serve as the input to a detailed design of an experimental model.
