Abstract:
Zhongshan Station perennial satellite positioning tracking station is China's domestic satellite tracking network to the southern tip of the expansion of the Earth, both of China's satellite orbit determination or research, are very important to add, at the same time, China's participation in the window of the Antarctic cooperation. Antarctic geodesy research is based on the framework of the
... structure of SCAR (ICSU Antarctic Scientific Research Committee) was organized and implemented an international large-scale scientific research cooperation projects.
The project began in 1992, conducted on an annual basis for 22 days the entire Antarctic GPS measurement battle together, our two stations since 1994 to participate. Its aims:
(1) Measurement of the Antarctic plate quickly with the adjacent panels, as well as micro-plate faster faster the relative motion between the rate and direction of movement;
(2) to identify the various internal Antarctic plate crust block the relative motion between;
(3) reunification of the Antarctic, the vertical system of benchmarks to determine the Antarctic tide gauge stations of the 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" respect scientific research.
In late 1998 of China's Zhongshan Station in the Battle of the SCAR GPS observatories built a perennial GPS satellite tracking station, the purpose of obtaining long-term follow-up site, a large number of, the original GPS system observational data through scientific calculation and comparison, access to GPS tracking site position in space with time resulting trajectory for the Antarctic region, geodynamics, geophysical structure and study the Earth's shape to provide information and data; and the Antarctic region precision positioning control points to provide quality date and reliable data. At the same time, the station of observational data on the analysis of satellite tracking technology to improve the accuracy of China's satellite orbit determination are useful.
