SCAR (03-04) Epoch GPS Campaign

Antarctic plate movement monitoring geodynamics research into the problems of the international Antarctic concern to scholars over the years large-scale, long-period research project belonging to the Antarctic environment of long-term changes in the areas of study. Beginning in 1992, SCAR organize and coordinate a dozen countries participated in more than 30 Antarctic stations consecutive annual 22 days of the Antarctic GPS measurement battle together. Our country from the "Eighth Five-Year Plan" to begin this research in the field of Antarctic two stops from the beginning of 1994 to participate in the international cooperative research.

GPS international joint testing by ICSU's Scientific Committee of Antarctic Geodesy and Geographic Information Working Group (SCAR-WGGGI) organization and implementation of an international large-scale cooperation projects. Its purpose and significance lies in:
1) Measurement of the Antarctic Plate and the adjacent plate, as well as micro-plate relative motion between the rate and direction of movement;
2) to identify all the Antarctic plate to the internal relative motion between the shell;
3) reunification of the Antarctic, the vertical system of benchmarks 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, "the interaction of global and Antarctic" scientific research.

The International Alliance GPS measurement time for the 2004 1 on 20 day 00:00 (UTC) -2004 In February 10
24:00 (UTC), a cumulative time of 22 days, observing day of January 13 to February 17, more than the stipulated time observation for two weeks. Every six hours every day to check the work of an instrument, to change every two days battery backup to ensure adequate back-up battery power. Observation period, three power stations, but the backup battery fully prepared, no power outages occurred apparatus. Daily 23:50 (UTC), on time and the work of inspection equipment, ready to shut down and transfer data. 23:59 shutdown, and quickly check whether the antenna in the leveling and high volume of check antenna. 0:01 the next day replacement of permit boot, to continue the second day of observation.
