초록

우리나라에서 개발 중인 저궤도 위성은 아리랑 위성으로, 이제까지 꾸준한 성능향상이 있었다. 이때 탑재체의 성능향상에 따른 탑재체의 전력요구도는 늘어나게 되었고 이에 위성 내부 전력 공급장치의 설계 및 Solar Array의 구성 등 위성 설계가 달라진다. 이에 따라 위성에 전력을 공급하며 위성 통합시험을 진행하는 전력계 전기지상지원장비 설계 시 전력 증가에 따라 많은 고려사항이 필요로 한다. 본 논문은 탑재체에 따른 위성 전력요구도의 변화 및 전력요구도 증가에 따른 전력계 전기지상지원장비 설계 시 고려할 사항에 대해서 다룬다.

KOMPSAT (Korean Multi-Purpose Satellite) is a Low-Earth-Orbit (LEO) satellite under development in Korea. Its performance has been steadily improving. At this time, power demand of the payload increased according to performance improvement of the payload. Accordingly, design of the satellite, such as design of the internal power supply device and the configuration of the solar array, was changed. Thus, many considerations are required according to an increase in power when designing power EGSE (Electric Ground Support Equipment) for supplying power to satellites and conduct satellite integration tests. This paper deals with matters to be considered when designing power EGSE according to changes in satellite power requirements according to payloads and increase in power requirements.
