Control Moment Gyroscope is used to control the attitude of a spacecraft.

Control Moment Gyro is essentially an actuator generating torque based on gyroscope principles, and has the advantage of producing large torque output with low power consumption. Control Moment Gyro is the most effective gyroscope for reconnaissance satellites which conduct high maneuver, multi-target image acquisition missions.

Applied research on Control Moment Gyro wheels (core technology) is currently being conducted.
