PROBLEM TO BE SOLVED: To always detect and control its own yaw angle by a simple process by communicating with the other artificial revolving on the same orbit at a fixed relative position, and correcting the coming direction of the signal of roll and pitch angles and the relative position of the two satellites. SOLUTION: When a first artificial satellite 1 and a second artificial satellite 50 revolve on the same circular orbit, the relative position is comparatively not changed, because the second artificial satellite 50 is stationary in the range of vision of a receiver 54, the first satellite 1 and the second satellite 50 can be always visible to each other. Hereby, independently of the orbital position of the first satellite 1, the yaw angle 24 can be always stably detected, and an attitude control circuit 13 is unnecessary to be corrected by changeover of sensors and control systems due to the orbital position or seasons, and hence the yaw angle 24 can be controlled by a simple method.
