| Abstract: | Datum unity in GPS precise data processing was discussed in this paper. Theories of unifying datum in baseline processing and adjustment processing were declared respectively, and the difference of 3D speed valuations calculated by those two methods was analyzed by case study. As a result, the second method was recommended to process GPS precise data in present-day crustal movement velocity field research. |
