To support the operation of onboard AOCS (Attitude and Orbit Control System) of "SAKIGAKE" and "SUISEI", ground support software for attitude control and orbit correction was developed. The software, named POPS (PLANET-A AOCS Operation Software), has the function of (1) generating the commands for RCS thruster control and HGA (High Gain Antenna) despin control, (2) simulating spacecraft attitude dynamics to confirm the generated RCS control commands. (3) performing orbit correction analysis to provide the optimum ⊿V-maneuver under various maneuvering constraints, (4) estimating RCS fuel consumption, and (5) conducting the calibration of RCS thrusters. In this paper the functions of POPS are described in detail. The operational results of "SAKIGAKE" and "SUISEI" in orbit are also presented.
