摘要

本文采用山西省连续运行参考站系统(CORS)网中各站点的观测数据,基于不同版本数据预处理软件(TEQC)对观测数据进行了质量检查研究.结果表明,TEQC软件新版本检查结果更加稳定,多卫星系统数据理论观测历元数在截止高度角15°及以下占比较大,在截止高度角15°及以上,不良卫星影响因子大于截止高度角影响因子.TEQC软件版本差异分析结果可为全球导航卫星定位(GNSS)数据预处理及基线解算提供一定的应用参考价值.

Abstract

This paper utilized the observation data from each station of the continuous operational reference system(CORS)in Shanxi Province and carried out quality inspection research on the observation data based on different versions of data preprocessing software,namely translation,editing and quality checking(TEQC).The results indicate that the new version of TEQC has more stable inspection results.The theoretical observation epoch number of multi-satellite system data is relatively large at cut-off altitude angles of 15° and below.At cut-off altitude angles of 15° and above,the influencing factor of the adverse satellite is greater than that of the cut-off altitude angle.The difference analysis results of TEQC in different versions can provide certain application reference values for global navigation satellite system(GNSS)data preprocessing and baseline calculation.
