我国GPS跟踪站数据处理与时间序列特征分析

Data Processing and Time Series Analysis for GPS Fiducial Stations in China

应用国内GPS跟踪站7 a的观测数据,分析研究跟踪站坐标位置变化规律,并给出了站坐标和速度场精度的统计分析结果,同时介绍了国内GPS基准站的数据处理方法。通过对时间序列进行分析研究表明,GPS基准站的时间序列具有一定的周期性,高程分量的周期性最为明显,并且时间序列的时频特性表现出明显的区域性。

On the basis of the observation data provided by domestic GPS fiducial station, coordinate variety rules of GPS fiducial station are analyzed, and a statistic analysis result of station coordinates and velocity precision is obtained. Meanwhile the data processing method for domestic GPS fiducial station is introduced. It indicates that the time series of GPS fiducial station has some periodicity, especially the periodicity of elevation direction; further more, the frequency of time series shows distinct regional nature.
