Abstract

Korean ground systems have started to be developed for mission control and payload data processing since 1990s. International technology cooperations were needed in the early development phase of ground system for science experiment satellite, LEO satellite and GEO satellite and then they have been developed as domestic own technology since acquiring early technology. Our country has developed total 14 ground systems until now, this paper suggests prospect and direction on ground system development in the base of such development experiences. Mission control system is needed to develop multi-satellite mission control system in the base of technology of re-configure, re-use and automation. Processing system is needed to acquire processing technology for kinds of payload sensor data and study inter-operation to integrate and use outputs which are processed between users. Finally, national ground system infrastructure is needed to operate kinds of lots of satellites at worldwide area.

우리나라 지상시스템은 위성 관제와 탑재체자료 처리를 위해서 1990년대부터 개발되기 시작하였다. 과학위성, 저궤도위성 및 정지궤도 지상시스템의 초기 개발 시에는 국제기술협력 등이 필요하였으나, 초기 기술 확보 이후에는 국내 독자 기술로 개발되기 시작하였다. 우리나라는 지금까지 총 14기의 지상시스템을 개발하였으며, 본 논문은 이러한 경험을 바탕으로 발전 전망 및 방향을 제시한다. 관제시스템은 재구성, 재사용, 자동화 기술을 기반으로 하는 다중위성 관제시스템 개발이 필요하다. 처리시스템은 다양한 탑재체자료 처리 기술의 확보와 처리정확도 향상을 위한 검보정 기술의 접목이 필요하다. 또한, 탑재체 자료 양의 증가로 인한 고속처리 기술 확보와 처리된 탑재체자료를 사용자 간에 사용하고 통합하는 상호운영성 연구가 필요하다. 끝으로, 다양한 종류의 많은 위성을 운영할 수 있도록 국내외에 분포된 안테나 등 국가 지상시스템 인프라 망 구축이 필요하다.
