A spacecraft is provided which has an environmental disturbance torque filter that predicts the environmental disturbance torque acting on the spacecraft, and an unloading control section 5 which establishes, from the predicted environmental disturbance torque 4 and the angular momentum residual 2, a magnetic moment to be generated, by considering the environmental disturbance torque, thereby providing a reduction in magnetic unloading power consumption and a reduction in the size and weight of related hardware.
[ What is claimed is:] [1.] A spacecraft which includes aboard it an attitude control system, this attitude control system comprising:means for accumulating angular momentum residual;means for detecting angular momentum residual;a filtering means for performing environmental disturbance torque prediction filtering, which predicts an environmental disturbance torque from said angular momentum residual;means for performing magnetic unloading control, to which is input said angular momentum residual and said predicted environmental disturbance torque, and w...
