Suppose you have a reaction wheel or a control moment gyroscope on your spacecraft for attitude control. This would be a self contained unit, with 3-axis control. Either device utilizes the conservation of angular momentum, trading angular momentum between the unit and the spaceship frame as needed for attitude control.

Does the placement of the reaction control unit matter? Should it be as close as possible to the spacecraft 's center of mass for the best effect?
