SCAR (04-05) Epoch GPS Campaign

GPS international joint testing by ICSU's Scientific Committee of Antarctic Geodesy and Geographic Information Working Group (SCAR-GSSG) was organized and implemented an international large-scale cooperation projects, whose aim is the sharing of data through observation, research:
1) the Antarctic plate and adjacent plates, as well as micro-plate relative motion between the rate and direction of movement;
2) the Antarctic plate various places within the relative motion between the shell;
3) a unified system of vertical Antarctic base to determine the tide of the Antarctic station elevation above sea level;
4) as a result of melting ice sheets and marine load caused by the change of the Antarctic lithosphere, such as vertical movement of the "global interaction with the Antarctic" and other scientific issues.

China's participation in international GPS campaign observation, not only can the international sharing of the study results, but also the international joint testing data sharing power, for raising the level of China's Antarctic research Geodynamics, expanding the research in the field of international influence and of great significance .

The International Alliance GPS measurement time for the 2005 1 on 20 day 00:00 (UTC) -2005 years February 10 24:00 (UTC), a cumulative time of 22 days, 24 hours a day for observation.
The joint test used by the Wuhan University of Surveying and Mapping Institute of Trimble GPS receiver, it has L1, L2 dual-frequency phase output, for the international advanced, high-precision, the international joint testing and the global number of IGS (International GPS Service) station commonly used.
