区域GNSS控制网成果更新方案探讨及精度分析

Discussion and Accuracy Analysis on the Results Updating Scheme of Regional GNSS Control Network

区域GNSS控制网作为测量控制、形变监测、环境科学和地球科学研究的参考,其坐标成果准确性十分重要,为了保障坐标成果的准确性,需定时进行控制点的重新埋设并更新成果。本文研究了三种区域GNSS控制网的成果更新方案,并进行精度分析。研究结果表面,三种区域GNSS控制网成果更新方案均能达到设计要求,在对区域GNSS控制网成果进行更新时,可根据实际情况选取其中一种方案进行区域GNSS控制网成果更新。

The regional GNSS control network is used as a reference for control survey, deformation monitoring, environmental science and earth science research, the accuracy of its coordinate results is very important. In order to ensure the accuracy of the coordinate results, it is necessary to re-embed the control points and update the results regularly. In this paper, three regional GNSS control network results updating schemes are studied, and the accuracy is analyzed. The research results show that the three regional GNSS control network results update schemes can all meet the design requirements, when updating the regional GNSS control network results, one of the schemes can be selected according to the actual situation.
