摘　　要：从提高导航系统性能出发,阐述了多卫星系统,卫星系统完整性和最佳定位卫星组合的选择等问题,研究了基于伪距、伪距率的SINS/卫星组合导航的模型,并对SINS/GPS/GLONASS/GALILEO/BD组合系统进行了仿真。通过与SINS/GPS组合系统仿真结果对比表明,SINS/多卫星系统组合对导航系统性能具有更好地提升作用,且对于提高导航系统的可靠性、安全性有较大帮助。To improve the integrated navigation performance, the paper described some important issues, such as multi satellite system, satellite system integrity, combination of the best positing satellites, and so on, studied the model of SINS/satellite system integrated navigation system based on pseudo-rang and its’ rate and simulated the SINS/GPS/ GLONASS/GALILEO/BD integrated navigation system. By Comparing with the simulation results of SINS/GPS, It was shown that the performance of navigation system was greatly improved by using SINS/multi-satellite system rather than just SINS/GPS, and it also much more enhanced the reliability and security of the navigation system.
