gimballed momentum wheel: Better attitude control and energy storage can be achieved by using a pair of counter-rotating micro wheels. This configuration enables micro-satellites to change their angular momentum and orientation with very little net change in stored energy. Likewise, energy can be extracted or added to a pair of wheels without changing the satellite's attitude. Power can be saved while using a regenerative brake state to decrease the speed, or this braking energy can be used to accelerate the other micro-wheel rotating in the opposite direction in a gimballed momentum wheel. Thus, it can sustain spacecraft with limited power during a short-term space mission.  2, fiche 1, Anglais, - single%2Dgimballed%20momentum%20wheel
