To jet only a thruster having no cancellation between control torque by distributing a control torque command signal necessary for the control of two axes of an artificial satellite to a diagonal thruster group by coordinate transformation or the like based on thruster disposition.

By transforming a control torque command calculated by the coordinate system of a satellite into a coordinate system determined in accordance with thruster disposition, each thruster generates torque for controlling only one axis in the coordinate system based on the thruster disposition, and in the case of controlling two axes simultaneously, in the satellite coordinate system, only effective thruster control torque having no control torque interference between the axes is generated.
