GPS监测网数据质量分析

Research on data quality analysis of the GPS monitoring network

为保证GPS监测网络满足监测精度要求,本文提出了GPS外业数据采集、基线解算应采取的措施及数据处理方法。并对两期观测数据及处理结果进行质量分析,以保证变形分析的可靠性。

In this paper, the measurements of collecting GPS data and soluting baselines, and the methods of GPS data processing are put foreward to satisfy the accuracy requirement of the monitoring network. In order to guarantee the reliability of the deformation analysis, the quality of two terms observations and their results is analyzed.
