Since reaction wheels are internal momentum exchange devices they can’t alter the total angular momentum of the satellite. But the angular momentum of the satellite can be redistributed between the wheels and satellite body. The total Therefore the required amount of angular momentum of whole satellite can be transferred to the wheels making the angular momentum of satellite body zero. <br \>[[File:Equation50in order to achieve the desired attitude rates.png|frame|center]]
