WitrynaControl-moment gyroscopes (CMGs) have been used for attitude control on spacecraft that require large torques. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft.
