WebDec 23, 2014 · The solution is simple: Set the reaction wheels in motion, against the direction the spacecraft needs to rotate. The spacecraft will begin rotating in the desired direction. The reaction wheels' rotations are stopped when the spacecraft reaches the desired orientation. There are problems with this simplistic view. Single-gimbal The most effective CMGs include only a single gimbal. When the gimbal of such a CMG rotates, the change in direction of the rotor's angular momentum represents a torque that reacts onto the body to which the CMG is mounted, e.g. a spacecraft. Except for effects due to the motion of … See more A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. … See more CMGs differ from reaction wheels. The latter apply torque simply by changing rotor spin speed, but the former tilt the rotor's spin axis without necessarily changing its spin speed. CMGs are also far more power efficient.
