The Visual Simulation System Based On Satellite-Borne GPS Satellites Formation Flying

Aimed at study of the effect on formation flying using the algorithm and model for autonomous navigation based on satellite-borne GPS satellites,this paper designed a basic simulation system based on satellite-borne GPS satellites formation flying in which database system was used.On a basis of the law of satellites formation relative navigation,this paper simulated the space circle formation simulation,wheel formation and horizontal circle formation by using OPENGL language and database technology.The process of design was given.Considering the autonomous navigation of formation satellites based on receiving GPS signal,the visibility GPS constellation was simulated using GPS visibility analysis.The trajectory of formation satellites have been validated by STK.The software was used as a basic tool for designing formation flying and designing relative navigation algorithm of formation flying.The method will provide the basis data and technology for all kinds of spacecraft formation flying and for space vehicle rendezvous and docking.
