1. An attitude control, comprising:a control momentum gyro comprising an internal gimbal, a rotor on said internal gimbal, a motor for rotating said rotor, a motor speed control for said motor, means for moving said internal gimbal and an actuator control; first signal processing means for providing a first signal to said motor speed control to change the speed of said motor in response to a disturbance mitigation signal and for providing a second signal to said means for moving said internal gimbal to change the attitude of a satellite in response to an attitude control signal; a sensor for providing a gimbal motion signal manifesting the motion of said internal gimbal; and second signal processing means that receives said gimbal motion signal for detecting noise in said gimbal motion signal and for providing said disturbance mitigation signal to cause the rotor speed to change to reduce said noise in the motion of said internal gimbal.
