摘　　要：组合中国北斗(BDS)、美国GPS、俄罗斯GLONASS和欧盟GALILEO 4个全球卫星导航系统,通过仿真数据对比GPS单一系统、当前组合系统、未来完整组合系统在全球不同纬度地区几何精度衰减因子和导航精度的变化情况,分析组合卫星导航系统的优势。In this paper, an integrated navigation system which included the Chinese BDS, the U.S. GPS, the Russian GLONASS and the EU's GALILEO was applied to be simulated. The simulated data was used to compare the current single GPS system, the current integrated system, future complete integrated system in global area's GDOP and navigation accuracy, and analysis the improvement of the integrated satellite navigation systems in GDOP and navigation accuracy.
