PROBLEM TO BE SOLVED: To provide an orbit attitude control technique robust against disturbing factors.SOLUTION: An orbit attitude control device is equipped with a divert thruster including a plurality of nozzles. Among the plurality of nozzles, first group nozzles jet combustion gas in mutually opposite directions along a first axis, and second group nozzles jet the combustion gas in mutually opposite directions along a second axis. A control part calculates a correction value for an opening degree command value for each of the plurality of nozzles, and corrects the opening degree command value based on the correction value. The orbit attitude control device is further equipped with a first axis acceleration sensor for detecting an acceleration in the first axis, and a second axis acceleration sensor for detecting an acceleration in the second axis. A correction value of an opening degree of each of the first group nozzles is determined based on the first axis acceleration, and a correction value of an opening degree of each of the second group nozzles is determined based on the second axis acceleration. |
