| Abstract: | This paper adopts two different softwares--GAMIT and GrafNav respectively to calculate GPS precise point positioning data, which observed in different time and different place of South China Sea area, and contrasts precision about calculated result of the same data. The final analysis indicates that the margin of the results calculated by both of the methods can reach centimeter. So it shows GrafNav software can be used to calculate GPS data of precise point positioning, and it also indicates that the method calculated by GrafNav software is effective and valuable. |
