摘要
目前我国已经在全国范围内建成了众多不同级别的CORS站网,但不同CORS网络间尚未实现并网,不能跨区域提供网络RTK服务,给实际生产带来不便,同时制约数据融合、科学研究和协同服务。为解决这一问题,本文提出划分子网并进行子网数据共享的方式,实现区域CORS系统联动数据处理,并进行实地采集数据测试应用效果,结果表明:在实现了基准统一和跨界区域数据共享的基础上,新的网络RTK实时定位服务能够对跨界区域用户提供同等精度的定位和导航服务。
At present our country has built many different levels across the country the CORS station net, but has not yet been realized between different CORS network, can't provide network RTK service across regions, causing inconvenience to the actual production, at the same time restricted data fusion, scientific research and service together.In order to solve this problem, this paper proposes the method of dividing subnet and sharing subnet data, realizing the linkage data processing of regional CORS system, and conducting field data collection to test the application effect. The final result proves that the new network RTK real-time location service can provide the same precision location and navigation service for the users in the cross-boundary region on the basis of the unified benchmark and data sharing in the cross-boundary region.
