跨区域CORS系统基准站选址测试数据处理与分析研究

Research on Processing and Analysis of Reference Stations Testting Data During Cross-regional CORS Setting up

讨论了跨区域CORS系统建设过程中基准站站址测试数据处理的流程与方法,提出了从观测数据完好性、数据质量、单点定位结果以及基线解算等四个方面对CORS系统基准站选址进行分析与评价,并结合武汉城市圈CORS系统建设的实例进行分析。通过实测数据的处理,表明本文提出的CORS系统站址测试数据处理方法能够较客观地反映基准站的观测环境和外界干扰情况,对保障CORS系统的连续正常运行具有积极意义。

This paper discusses the processing of reference stations testing data during setting up CORS,.and indicates from four ways to analyse and appraise the data quality of reference stations,which are data integrality,the analysis of multipath,the results of single point positioning and baselines computing.Results of Wuhan metropolis continuously operating reference station show that the methods can factually reflect the observing circumstance and the outside influence.of reference stations.
