To eliminate a risk that the number of objects in orbit continues to increase in a case where the amount of propellant has decreased more than planned.SOLUTION: A ground facility controls an artificial satellite including a propulsion device. The ground facility adopts a propellant management method in the artificial satellite. The propellant management method includes: on the basis of the number of years Lx of operation of the artificial satellite in orbit up to the present time and the amount of propellant at the present time, calculating whether the amount of propellant at the present time is the amount of propellant required to enter the atmosphere in less than Lx years from the present time; and determining the termination of operation of the artificial satellite in orbit, on the basis of the amount of propellant required to enter the atmosphere in less than the Lx years from the present time.SELECTED DRAWING: Figure 14
【課題】推薬量が計画よりも減損した場合に軌道上物体数が増え続けてしまうリスクを解消することを目的とする。【解決手段】地上設備は、推進装置を具備する人工衛星を制御する。地上設備は、人工衛星における推薬管理方法を採用する。推薬管理方法では、人工衛星の軌道上での現在までの運用年数Lxと現時点での推薬量とに基づいて、現時点での推薬量が現時点からLx年未満で大気圏突入に要する推薬量かを算出し、現時点からLx年未満で大気圏突入に要する推薬量に基づいて、人工衛星の軌道上運用の終了を判定する。【選択図】図14
