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. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft. [1] [2]

Prior to CMG activation, the ISS attitude control was accomplished using thrusters. Thrusters are now used as a backup for CMG control, for large attitude maneuvers, or for translational control. Nominal quiescent operations are handled by the CMGs using a …

This paper describes the Space Station Double Gimbal Control Moment Gyroscope design, on-orbit telemetry signatures and a summary of the results of both failure investigations. The lessons learned from these combined sources have lead to improvements in the design that will provide CMGs with greater reliability to assure the success of the ...

Harnessing momentum with precise, powerful control. Single-gimbal Control Moment Gyroscopes (CMG) offer significantly greater vehicle acceleration (>100x) than a reaction wheel system of the same power. However, controlling an array of CMGs is a difficult task.

Jul 1, 2023 · The Control Moment Gyroscope (CMG) is a device used on the International Space Station (ISS) to control its orientation in space. It utilizes momentum exchange between spinning wheels to generate torque, allowing for precise and efficient attitude adjustments of …
