Abstract

Currently we have an electro-optical space object monitoring system (OWL-Net) developed by the Korea Astronomy and Space Science Institute as the only ground-based on orbit space object tracking capability in Korea. This system can produce the ephemeris of domestic satellites and survey the geosynchronous orbit region. As the number of observation objects increases and the operation condition get worse, a low budget dedicated monitoring telescope capable of full time geosynchronous orbit region survey can support an effect operation of the OWL-Net. In this study, we analyze the requirements of a low-budget dedicated optical monitoring system for geosynchronous orbit region without the degradation of observation quality to increase the risk of corrupted ephemeris.

현재까지 국내에서 궤도 상의 자국 우주 물체를 지상에서 추적할 수 있는 시스템은 한국천문연구원에서 개발 중인 우주물체 전자광학 감시체계가 유일하다. 이 시스템은 자국 저궤도 위성의 궤도력 산출과 현재 대한민국에 할당된 정지궤도 영역을 감시하는 기능을 보유하고 있다. 그러나 관측 대상이 확대되고 운영 조건의 변화에 따라, 국내 정지궤도 영역 상시감시가 가능한 저예산 보조관측 시스템은 전체 우주 감시시스템의 매우 효율적인 운영을 지원할 수 있다. 따라서 저예산 시스템의 관측정밀도 저하에 따른 궤도력 산출의 위험도 증가를 억제할 수 있는, 지구 정지궤도 영역 상시 감시용 전용 광학관측 시스템의 요구사항을 분석했다.
