南方单基站CORS在校内控制测量中的应用

The CORS of south single base station in school control measurement

连续运行卫星定位系统(CORS)与传统的GPS定位相比,具有操作简单、成本低、精度高、实时性强、覆盖率广等优点,特别是CORS内网络RTK测量功能的实现,极大地提高了测量工作效率.利用南方CORS系统,获取了校园建设和实习控制点的坐标,并且通过GPS静态定位结果和RTK测量结果对比分析,发现南方单基站CORS获取的平面坐标精度达到了校园控制测量的要求,可为后续学校的操场建设和校内实习测量以及科研项目的外业数据采集提供有力的技术支持.

Compared with the traditional GPS positioning ,the continuous operational reference system (CORS) is simple ,low cost ,high precision ,real-time ,and wide coverage .The imple-mentation of the RTK measurement functions within the CORS network greatly improves the measurement of productivity .In this paper ,We use southern CORS system to obtain the coordi-nates of campus and internships control points .Comparied with GPS static positioning results , the RT K measurement results show that the base plane coordinate precision of southern single base station CORS reaches the requirements of campus control measurement and it can provide a strong technical support for data a cquisition of follow-up school palygrouds construction ,campus internships and research projects cuside work .
