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

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.
