北斗卫星导航地基增强系统设计与测试分析

Design and test analysis of Beidou satellite navigation foundation enhancement system

文章首先回顾、总结了全球卫星地基增强系统的产生、发展和演化情况,介绍了我国北斗卫星地基增强系统的现状;其次,对网络RTK的误差和影响定位精度的因素进行了剖析研究,并以新疆地区为例,分别将北斗卫星地基增强系统与移动网络定位和GPS系统定位精度进行对比;最后,将北斗系统与GPS系统组合定位精度进行评估,探索北斗卫星地基增强系统的定位效果。

This paper briefly reviews and summarizes the generation,development history and evolution of the global satellite foundation enhancement system,introduces the current situation of the Beidou satellite foundation enhancement system in China,analyzes the error of the network RTK and the factors affecting the positioning accuracy,then compares the Beidou satellite foundation enhancement system with the mobile network and the positioning accuracy of the GPS system,and explores the positioning effect of the Beidou system and GPS system.
