摘要
随着中国大陆构造环境监测网络(陆态网络)260个GNSS连续观测基准站在全国范围内的建成与运营,给三级GNSS大地控制网布设及数据处理带来了诸多方便,解算精度有一定的提高,图形结构更加合理,同时对基准站的选取提出了更高的要求,本文通过实际试算统计分析说明三级GNSS大地控制网数据处理时如何选取连续运行基准站、图形结构对解算结果及精度的影响。
With the development of CMONOC including 260 GNSS CORS stations, the Level 3 control network data processing is much more convenient. The accuracy of results is improved, and the geometric distortion is more reasonable. However the standard a- bout selection of base stations is higher. This study discusses how to choose base stations, and the effect of geometric distortion to the accuracy of results.
