高精度地壳运动监测GNSS基准站数据质量评价方法分析

EVALUATION METHOD ANALYSIS OF GNSS BASE STATIONS DATA QUALITY IN HIGH PRECISION CRUSTAL MOVEMENT OBSERVATION

通过GNSS观测试验和大量数据质量分析实践,论证总结了一套综合的用于高精度地壳运动监测的GNSS数据质量分析方法,包括站点地基类型、数据有效率、多路径效应、卫星天空图、相位残差、站点位置时间序列分析以及速度场背景趋势等,为GNSS站点建设、运行维护、数据处理和地壳形变监测应用提供参考基础。

According to test of GNSS observation and lots of data quality analysis, this study demonstrates and summarizes a set of GNSS data quality analysis method apply for high precision crustal movement observation, including basement style of station, data availability, multipath effect, satellite sky map, phase errors, time series of station displacement, velocity profile background trend and so on. Those methods supply a reference base for construction of new stations, operating maintenance, GNSS data processing and crustal deformation monitoring application.
