摘　　要：借鉴 INS/GPS 组合导航系统原理,文中提出了 SINS/速度组合导航系统方案.在此方案中,利用基地辅助测速测得的速度信息作为导航系统的辅助信息,通过 Kalman 滤波来修正 SINS 系统的误差。仿真结果表明:组合系统导航精度基本达到目前实际应用的水平。应用此方案,只须利用能够提供速度信息的低成本基地辅助测速系统(空基如高空气球等空中平台,陆基如雷达站等)就能实现导航定位的功能,具有实际应用前景和深远意义。Through making the research of INS/GPS integrated navigation system,this paper has put forward the scheme of SINS/velocity integrated navigation system.In this scheme,only utilize the velocity received from the base assistant velocity measurement as the additional information of integrated navigation system,through Kaiman filtering correct the error of SINS system.The simulation result shows:The navigate precision of integrated navigation system reaches the level that at present using actually basically.Use this scheme,we need only utilize the base assistant veloci- ty measurement(space-based such as high altitude balloon,etc.platform in the sky;ground-space such as radar,etc.) which can offer velocity information to realize the function of orientation and navigation.It has practical prospect and far-reaching meaning.
