IFAC-PapersOnLine, 2018 Abstract Modern Earth observation spacecrafts require high agility to maneuver with larger torque which eventually needs CMGs, as Reaction Wheels cannot meet the demand of such large torques. In order to obtain high-accuracy pointing control with CMG, extremely precise gimbal control is necessary.
