基于北斗的多系统组合定位方法研究

基于多系统组合的导航定位技术应用日益广泛，采用多系统组合导航克服了单一星座系统定位中存在的定位精度差、可见星少、可靠性低等问题。本文提出了基于北斗卫星导航系统的多系统组合定位方法，详细推导了基于北斗的多系统组合用户定位算法模型。比较分析了单一北斗卫星导航系统和北斗、GPS、Galileo 多系统组合条件下服务性能，得出在多系统组合条件下可以极大改善用户观测条件，进而提高了用户导航定位使用效能。

Research on Multi-System Integrated Position Based on Beidou

Application of multi-system integrated position became more popular. The single of navigation system has low position accuracy, less visible satellites and low reliability. The position algorithm of multi-system integrated position was studied in the paper. Simulation results indicate that multi-system based on Beidou/GPS/Galileo can greatly improve the position precision, reliability and more visible satellites. The research can improve the user of position and navigation availability.
