Three-Dimension Visual Simulation System Based on Satellites Formation with Satellite-Borne GPS

The three-dimension simulation of satellites formation is a system engineering. It can give intuitive graphics by 3D views and intuitive data by database, which convenient for our research. For this, we designed simulation system process chart and other diagrams. In this paper, we take the simulation of space circle formation for satellites as an example. Using dynamic equation and OpenGL, the relative positions,space trajectory and ground track of formation satellite can be viewed and the visibility GPS constellations is simulated. Using SQL server 2000, we can call the data at any moment which can be reference data for relative navigation algorithmic. The software can be used as a basic tools for designing formation flying and selecting the relatively navigation algorithm of formation flying.
