- W2395581965 abstract "국내의 위성 개발 프로그램은 정지궤도위성인 통신해양기상위성과 저궤도위성인 다목적실용위성으로 대별할 수 있다. 각 위성은 임무 요구조건을 충족하는 추진시스템을 탑재하고 있다. 통신해양기상위성에는 위성체의 지구정지궤도 진입, 자세 및 궤도 제어/조정을 위하여 요구되는 추력과 토크를 제공하는 이원추진제 추진시스템인 화학추진시스템이 탑재되어 있으며, 반면 다목적실용위성에는 궤도전이 기능이 배제된, 궤도상 자세제어가 주목적인 단일추진제 추진시스템이 장착되어 있다. 본 연구에서는 이 두 추진시스템의 차이점 및 특성을 비교 분석한다. Domestic satellite development programme is generally classified into two categories: COMS as GEO satellite and KOMPSAT as LEO one. Each satellite has the on-board propulsion system fulfilling its own mission requirements. The COMS propulsion system provides the thrust and torque required for the insertion into GEO, attitude and orbit control/adjustment of spacecraft. It is the well-known Chemical Propulsion System(CPS) using bipropellants. On the other hand, the monopropellant propulsion system is employed in KOMPSAT, and its main role is on-station attitude control excluding the orbit transfer function. In this study, these two representative propulsion systems are compared and analysed as well, in terms of essential differences and important characteristics." @default.
