Abstract：In order to verify the application effect of dynamic precision solution in the continuous motion platform such as earthquake,a dual frequency GPS receiver with the sampling frequency of 1 Hz was used, and the dynamic simulation experiments were performed in the orbit with the known parameters. The experiments were carried out on the dynamic platform for seismic simulation,and the experimental analysis was performed with the Track module in the GAMIT software. Through the precision processing of GPS data and the analysis for the base station data with the different distances,the motion trajectory diagram was obtained. The results show that the calculation accuracy of measurement points in both horizontal and vertical directions can reach the millimeter level by using the Track module,which means that the proposed calculating method can be applied in the actual dynamic measurement and can be used for inverting the dynamic change situation of ground surface when the earthquake occurs.
