The embodiment of the invention provides an antenna satellite-facing motion control method and device, an antenna system and a satellite system. The antenna satellite-facing motion control method comprises the following steps: acquiring a historical motion state of a target antenna; predicting a current motion state based on the historical motion state, and determining an estimated motion state; determining a state error between the estimated motion state and a target motion state according to the estimated motion state and the target motion state, the target motion state being determined based on trajectory data of a target satellite, and the target satellite being a satellite tracked by a target antenna; the influence factor of the state error on the torque is determined, the target torque is calculated according to the state error and the influence factor, and the influence factor represents the influence degree of the state error on the torque; and on the basis of the target torque, performing satellite motion control on the target antenna. And through multi-stage feedback and dynamic adjustment of the control moment, the tracking error is effectively reduced, and the precision and stability of the antenna tracking satellite are remarkably improved.
