摘要
现有CORS系统应用中GPS+GLONASS+BDS三星模式导航定位方面研究较少,且缺乏对不同模式的对比分析。本文从数据质量、RTK精度、恶劣环境等方面对苏州北斗地基增强系统进行检测,并对不同模式进行对比分析。苏州北斗地基增强系统各项指标满足设计要求;北斗系统的加入,有利于提高CORS系统的精度、时效性、空间可用性等,GPS+GLONASS+BDS三星模式应积极推广应用。
According to the fact that there is no enough research of the GPS ＋ GLONASS ＋ BDS Samsung mode navigation in CORS system, and lack the comparative analysis of the different modes. In this paper, the Suzhou compass ground - based system were test- ed and the different modes were analyzed by the data analysis, RTK precision test, bad environment test and other aspects. From these analysis, the indicators of the Suzhou compass ground - based system meet the design requirements, and the join of the Beidou system can really improve the precision, timeliness and space availability of the CORS system, GPS ＋ GLONASS ＋ BDS Samsung mode should be actively popularized.
