What Does CMG Stand For?

CMG stands for Control Moment Gyro

CMG, or Control Moment Gyro, is a type of gyroscopic device used for attitude control in spacecraft and satellites. It generates angular momentum to provide precise stabilization and orientation control by reorienting its spinning rotor. CMGs are vital for maintaining the desired orientation of spacecraft during maneuvers, allowing for efficient control without the need for traditional thruster systems. They are known for their ability to deliver high torque with low power consumption, making them a preferred choice in modern aerospace engineering.
