摘要
随着"数字城市"建设的进行,CORS网已经成为城市空间数据基础设施的重要组成部分,在高精度测量和位置服务中起到越来越重要的作用;而GNSS广域差分星基增强系统却没有得到快速的发展和大量的应用,普及范围远远不够。在此背景下,介绍了中国首套GNSS广域差分星基增强系统"中国精度",并对比分析了"中国精度"(Atlas)与CORS的差异与协作等。
With the development of Digital City construction in China,CORS has become an important part of urban spatial data infrastructure,and plays the more and more important role in high accuracy survey and LBS services.But satellite-based augmentation system has not been rapidly developed and widely used.It is far from enough popular.In this context,this article described the first Chinese set of SBAS named 'China CM',and compared the differences and collaborations of 'China CM'(Atlas) and CORS.
