Design of the Space-Based Optical Surveillance System Based on the Observation of Pinch Points Region on Earth Geostationary Orbit

In this paper, a space-based optical surveillance system was designed based on the research of geostationary (GEO) objects. Firstly, a strategy to observe the pinch point region was researched. Then, the orbit type of surveillance system and sensor pointing were analyzed, a equation set was deduced to guide the system design. The simulation result demonstrates that the revisit time of the surveillance system designed in this paper is less than one day, and the average coverage time is about 900s per day. The system can observe most of the GEO belt objects.
