| 摘 要： | 第一代北斗星座已经于2003年布置完毕，基本实现了中国本土及周边的导航定位功能。中国作为GALILEO卫星导航定位系统开发的重要参与者，研究北斗系统和GALILEO卫星导航定位系统的集成问题十分必要和迫切。本文，就第一代北斗星座对GALILEO卫星导航定位系统的增强性能进行分析，主要对PDOP指标进行了仿真。给出了国内典型城市的PDOP及其一天内的变化曲线。

| Abstract: | After the implementation of BEIDOU Constellation Satellites in 2003,the planned navigation and positional functions are basically acceptable.As one of the co-investors in the GALILEO navigation and positional system,it is impending and necessary for China to consider how to integrate and incorporate the two navigation systems,namely,the BEIDOU and the GALILEO.Herein,taking into account the both navigation systems,the PDOP for this hybrid navigation system is simulated.The PDOP for domestic typical cities are presented.Simulations have showed that regional improvement are obvious,however the global improvement is limited. |
