| 摘 要： | 目前国内建成的CORS系统以提供实时差分服务为主,对于毫米级的后处理,往往因为测站与基站的长距离需要测站长时间的观测,因此限制了CORS的应用拓展。本文通过CORS系统已知精确坐标、观测数据以及基准站间固定基线值,利用最小二乘内插方法,获取网内任意一点的空间相关误差,解决了虚拟基站的GPS观测数据的模拟,实现了CORS系统下测站与虚拟基站的短基线,从而能在短时间获取高精度的测站成果,并在苏州CORS系统下对研究成果进行测试计算及精度分析,得到了该模式下观测时间与定位精度关系的结论。

| Abstract: | At present,the built CORS system only provides the real-time differential service.Because of the long-distance between station and base station and needing enough observation time,the application of CORS is limited in the post process with mm level.This research used least-squares interpolation methods to obtain the space-related error of any point within the network,by using accurately known coordinates,as well as the baseline between actual observational data and the base stations in CORS,resolved the sim... |
