Abstract：Coupling with the data processing of ThirdOrder GPS Geodetic Network, unified adjustment is done using loose resolution obtained by ThirdOrder GPS Geodetic Network data processing and station network data. The improvement in coincidence of results was discussed. Minimum curvature grid interpolation method were used to calculate horizontal velocity field, of which the results were better comparing with the method of average velocity in district.Highprecision velocity field can reduce error in epoch reduction process.
