Abstract: Following the wide application of the HLA in the aerospace system simulation, the space-based surveillance distributed simulation system for the space targets based on the HLA is designed. In the infrastructure design level, the hierarchical structure including data layer, model layer and mission layer are designed. In the system design level, the simulation control members, space-based surveillance member, space target member, optical payload member, and visual simulation member are divided and confirmed. The orbit dynamics and maneuvering model, attitude dynamics and control model, payload pointing and optical imaging model are established. In system implement level, the distributed system is integrated based on the RTI. The space-based surveillance visual simulation and optical imaging simulation are realized by using the Vega Prime and OpenGL. The space-based surveillance for the space targets is simulated and verified finally.

Key words: space targets, space-based surveillance, HLA, visual simulation, RTI
