| 摘 要： | 研究了应用于铁路、内河水运等领域的分布式区域卫星导航系统定位方法。定位方法采用多站差分方式,分析了多站差分的误差特性、单参考站电离层和对流层误差,提出了基于伪距修正值投影的多站差分区域导航系统的定位方法。该方法解决现有技术中单差分系统用户与地面站的距离增加定位误差增大的问题,增加定位精度,同时提高系统的健壮性和覆盖效率。

| Abstract: | A positioning method of distributed area satellite navigation system is studied for railway and river transport.The method is composed of multiple differential reference stations,the pseudorange corrections project positioning method of multiple differential stations area navigation system is proposed based on the analysis of the multiple stations errors and the ionospheric and tropospheric errors of single reference station.This method resolves the single reference station difference positioning errors increase with the distance between the reference station with the user station.The positioning accuracy is improved,and robustness and overlay efficiency are increased. |
