Abstract On the basic of theory of PPP(Precise Point Positioning), we developed a program to calculate the ZTD, then we used the program and GAMIT to process the real observations.Compared the results with the data provided by the IGS, it is found that two methods both have high accuracy. Howver, the process results without faraway station data are of very low accuracy, it shows the advantage of Precise Point Positioning in the calculation of ZTD.
