A satellite (7) comprises thrusters (91, 92, 93, 94) disposed with the firing directions each facing away from the mass center of the satellite (7) and different from each other. An orbit determiner (8) determines mean orbital elements of the satellite (7) and temporal change rates of the mean orbital elements. A target value setter (1) sets target values of the mean orbital elements. A control amount calculator (2) calculates control amounts of the mean orbital elements from the mean orbital elements, the temporal change rates of the mean orbital elements, and the target values. A distributor (5) calculates firing timings and firing amounts of the thrusters for realizing the control amounts of the mean orbital elements by expressing a motion of the satellite (7) with orbital elements, solving an equation taking into account coupling of an out-of-plane motion and an in-plane motion due to thruster disposition angles and thruster firing amounts at multiple times, and combining one or more thruster firings controlling mainly an out-of-the-orbit-plane direction and one or more thruster firings controlling mainly an in-the-orbit-plane direction.
