PROBLEM TO BE SOLVED: To minimize the total length of thruster injection time in the attitude control of a geostationary satellite by computing the injection time of thruster from conditions of a roll torque command, pitch torque command, yawing torque command and the total sum minimum conditions of injection time. SOLUTION: A thruster injection device 10 is constituted of a software part 11 and a hardware part 12. For the attitude control of an artificial satellite, a torque command 15 is inputted to an attitude control 14 to a thruster injector 10. For the conditions of thruster injection, roll torque command conditions 16, pitch command conditions 17, and yawing torque command conditions 18 are set. The conditions are set with the addition of the total sum minimum conditions 19 of injection time. A computation means 20 determines a thruster injection time command 21 and transmits a signal to the hardware part 12 from the software part 11 of the thruster injector 10. Accordingly, the injection of thruster can be made to make the consumed fuel the minimum in generating control torque.
