摘要

摘要: 目的针对区域连续运行参考站网(continuously operating reference systems,CORS)组网中不同CORS坐标基准不一致的问题,分析了产生原因,给出了基准统一方法,并利用湖北、湖南两省CORS数据进行了实例分析。两省CORS坐标基准之间存在17.9±4.5mm的系统偏差,利用本文方法统一了两省CORS坐标基准,消除了系统偏差,实现了基准衔接。最后,针对区域CORS组网基准统一给出了若干建议。

Abstract: Objective In order to prevent the gaps in coordinate datum between different regional continuously op-erating reference systems(CORS),we analyze the causes and introduce a method for coordinate da-tum unification.Using experimental data from the Hubei and Hunan CORS,the results show that thesystematic deviation reaches 17.9±4.5mm between these two datums.The proposed method establi-shes a unified coordinate datum to eliminate the systematic deviation and builds connections betweeneach coordinate datum.The validity of our method was supported by empirical evidence.Finally,some suggestions about coordinate datum unification for a regional CORS network combination are putforward.
