沿海BDS CORS基准站选址关键技术研究探讨

Discussion on key technologies of location selection for reference stations of marine BDS CORS

为了提高沿海区域BDS精密定位服务系统的基准站选址精度,提出沿海BDS CORS基准站选址方法;通过论述沿海BDS CORS基准站布局设计和选址原则,以及现场踏勘与环境测试原理,将交通、通信、供电、防雷、机房及安保情况作为沿海基准站布局设计、初选和现场勘查的主要考虑因素,将观测数据完整性、多路径效应、信噪比情况作为基准站观测环境测试的3大主要指标,以期有效地解决沿海基准站的选址问题,满足实际工程需要。

In order to improve the accuracy of location section of the marine BDS CORS's reference stations,the paper proposed a secletion method:the principles of layout design and site selection,and the theories of reconnaissance and data test were introduced,traffic,telecommunication,electricity supply,lightning protection,machine room and security conditions were taken priority for the layout design,first site selection and reconnaissance of the marine reference stations,and observations data integrity,multiple routes effect and signal-to-noise ratio were used as three main indicators of the observation environment test of the stations.The research result would help effectively tackle the location seletion of marine reference stations for meeting the demands of practical projects.
