Abstract

This paper includes the development and operational status of the space object collision risk management system operated by the Korea Aerospace Research Institute. Currently, it monitors 6 low-orbit satellites and 3 geostationary satellites for collision risks 24 hours, enabling prompt collision avoidance maneuvers to ensure safe and stable operations. Since Chinese anti-satellite test (ASAT) in 2007, the monitoring of collision risks between space objects and operational satellites has been taken seriously, leading to the development of various collision risk management systems to respond quickly and efficiently to such situations. This paper provides an introduction to the space object collision risk management system developed from 2007 to the present, the current status of artificial space objects around Earth, and the system currently in operation. Additionally, it outlines future prospects and plans for the system.

본 논문은 한국항공우주연구원에서 운영 중인 우주물체 충돌위험 관리시스템의 개발 및 운영 현황을 포함하고 있다. 현재 저궤도위성 6기, 정지궤도위성 3기에 대해 24시간 충돌위험을 모니터링하고 있으며, 필요 시 충돌회피기동을 통해 충돌위험을 완화하여 안전하고 안정적으로 운영하고 있다. 2007년 중국의 자국위성 요격실험 이후 본격적으로 우주물체와 운영위성 간 충돌위험을 모니터링하고 있으며, 신속하고 효율적으로 상황에 대처하기 위해 다양한 충돌위험 관리시스템을 개발해왔다. 본 논문에서는 2007년 이후 현재까지 개발된 우주물체 충돌위험 관리시스템에 대한 소개, 현재 지구주변의 인공우주물체 현황, 현재 운영 중인 시스템에 대해 기술하였으며, 나아가 앞으로의 전망과 향후 계획에 대해 소개하였다.
