The only remedy for this loss of control is to desaturate the CMGs by removing the excess angular momentum from the spacecraft. The simplest way of doing this is to use reaction control system (RCS) thrusters. In our example of saturation along the forward axis, the RCS will be fired to produce an anticlockwise torque about that axis. The CMG control program will then command the rotor spin axes to begin fanning out away from the forward direction, producing gyroscopic torques whose resultant is clockwise about the forward direction, opposing the RCS as long as it is still firing and holding the spacecraft steady. This is continued until a suitable amount of forward angular momentum has been drained out of the CMG rotors; it is transformed into the moment of momentum of the moving matter in the RCS thruster exhausts and carried away from the spacecraft.
