摘要
为了进一步研究全球卫星导航系统,较全面地概述GPS、GLONASS、BDS和Galileo的发展历程和技术现状,并对四大系统技术进行比较分析。结果表明:全球卫星导航系统朝着兼容统一共享的方向发展;且通过高精度定位比较分析,说明GPS和BDS定位精度趋向相同。
In order to further study on global navigation satellite system,the paper introduced the development process and technology status of the navigation satellite systems including GPS,GLONASS,BDS and Galileo,and comparatively analyzed on the technology of the four systems.Results showed that GNSS is developing toward the direction of compatible and unified sharing;moreover,through the comparative analysis of high-precise positioning,it was known that the positioning accuracy of GPS and BDS could be the same.
