초록

정지궤도위성은 궤도상에서 위치변화를 제어하기 위해 추력기를 사용하고 운용수명에 맞추어 적정한 양의 액체추진제를 탑재한다. 그러므로 정지궤도위성의 수명은 추진제 잔여량에 좌우되고 정확한 잔여추진제량 측정은 조기 수명종료로 야기되는 경제적 손실을 완화시킬 뿐만 아니라 후속위성의 대체나 위성망 운용계획 등에 매우 중요하다. 잔여추진제량을 측정하는 방법은 주로 PVT 방법, 열질량법, 회계식 방법이 사용된다. 본 논문에서는 회계식방법을 사용하기 위한 천리안위성 이원추진시스템의 모델링과 몬테카를로 방법을 이용하여 천리안위성의 궤도전이 소요 추진제량을 분석하였다.

Geostationary satellites use the thruster in order to control the location change and mount the suitable amount of liquid propellant depending on the operating lifetime. Therefore the lifetime of the geostationary satellite depends on the residual propellant amount and the precise residual propellant gauging is very important for the mitigation of economic losses arised from premature removal of satellite from its orbit, satellites replacement planning, slot management and so on. The propellant gauging methods of geostationary satellite are mostly used PVT method, thermal mass method and bookkeeping method. In this paper, we analysis the modeling of COMS(Communication, Ocean & Meteorological Satellite) bipropellant system for bookkeeping method and COMS GTO(Geostationary Transfer Orbit) injection propellant estimation using Monte-Carlo method.
