【摘要】：2016年5月,千寻位置网正式公开运营北斗地基增强系统。作为国内首家商用北斗地基增强系统,千寻位置网可以为全国大部分范围内的用户提供高精度定位服务。本文首先介绍了千寻北斗地基增强系统观测数据的传输格式,然后在武汉、重庆两地分别对千寻北斗地基增强网络的RTK、RTD定位服务进行了性能测试。结果表明,其定位性能能够达到实时RTK厘米级和RTD亚米级,同时验证了解码程序的正确性。本文的研究内容对于北斗地基增强系统的应用推广具有一定的借鉴意义。
[Abstract]:In May 2016, thousand fathom site Network officially operated the Beidou Foundation Enhancement system. As the first commercial Beidou foundation enhancement system in China, thousand fathom location network can provide high precision positioning service for most users in China. This paper first introduces the data transmission format of thousand fathom Beidou ground Enhancement system, and then tests the performance of thousand fathom Beidou ground Enhancement Network in Wuhan and Chongqing. The results show that the positioning performance can reach the real-time RTK centimeter level and RTD sub-meter level, and the correctness of the decoding program is verified. The research content of this paper has certain reference significance for the application and popularization of Beidou foundation strengthening system.
