Lubrication of Attitude Control Systems
, 2011 The spacecraft attitude control system contains attitude error sensors such as gyroscopes and actuators such as momentum wheels and reaction wheels. The control moment gyros (CMG), in which the momentum wheels are mounted in gimbals, are also used in attitude control of spacecrafts. All these systems are designed to operate continuously till the end of
