摘　　要：针对研究星载GPS编队卫星自主导航算法及模型对编队的影响,为实际编队提高导航定位精度,结合数据库系统编制出了关于星载GPS编队卫星仿真系统。在分析卫星编队相对导航运动规律基础上,利用OPENGL及数据库技术对星载GPS空间圆编队,车轮式编队和水平圆编队进行了三维可视化仿真,给出了设计过程。考虑到编队卫星需要接收GPS信号进行自主导航,利用GPS星座可见性分析方法,实现星载GPS编队卫星的GPS星座选择。三维可视化仿真结合STK进行了验证。仿真系统已作为编队方案设计、编队飞行相对导航仿真算法设计的基础工具,还为将来各种航天器编队飞行应用技术及航天器对接技术提供可靠的试验基础数据和技术依据。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.
