PROBLEM TO BE SOLVED: To solve a problem that a CMG (control moment gyro) which is an actuator for the posture control of an artificial satellite can output large torque but increases a torque resolution and a torque output error. SOLUTION: This posture control device is provided with a CMG driving computing part 5 capable of outputting torque on an open loop and an RW driving control part to distribute torque to an RW (reaction wheel) 10 into the CMG in accordance with a gimbal angle of the CMG 4 and changes an open loop control mode by the CMG and a closed loop control mode by the RW over to each other at a maneuver time and at a non-maneuver time of the artificial satellite.
