摘要
网络RTK精度高、时效快,但部分区域无法进行实时网络RTK。基于山西省卫星导航定位基准服务系统建设的山西省快速精密定位平台,实现了基于基准站网的流动站双频GPS/BDS/GLONASS快速精密定位数据处理功能。从多系统组合解算、观测数据不同采样间隔和观测时长、野外大范围实测等多方面对该平台进行了精度测试分析。结果表明,该平台可以解决山西省弱信号地区的快速、高精度、可靠定位难题。
Network Real-Time Kinematic positioning technology could provide high-precision and effective positioning services.However,it would fail to obtain the positioning results in the areas where the communication link is out of service.In this study,we established the fast multi-GNSS data processing service based on the Shanxi Continuous Operating Reference Stations(SXCORS).Meanwhile,the accuracy is assessed by real data from the perspective of different GNSS combination,different sampling and different observing period etc.The results confirmed the high stability,reliability and efficiency of the real-time positioning services.
