Abstract: | The parameters of frame transformation from ITRF2005 to ITRF97 are deduced for calculation in this paper, and the frame transformation and epoch reduciton are researched deeply. With the data from the four IGS stations in China, the two transformation methods of frameepoch and epochframe are validated by examples. Finally this paper analyses the accuracy of conversion results and gives some suggestions for the use of coordinate transformation methods. |
