| |
| Abstract: | The Grove Mountains are located in Princess Elizabeth Land,East Antarctica,ext ending from 72° to 73°S latitude and 73° to 76°E longitude,covering approxi mately 8000 km～2 areas.During the 2002/2003 austral summer season,the 19th CH INARE(Chinese National Antarctic Research Expedition)carried out the third expedition in Grove Mountains,East Antarctica.The Geodetic network was establ ished,which can provide ground control for the satellite image map for the mult i-discipline expedition in the Grove Mountains where seven permanent GPS benchm a rks were set up supported by the helicopter and snow vehicles.All GPS sites bes ides Z001 were observed at least for one hour using the dual frequencies Trimble 4000ssi GPS receivers.The data were processed by the comprehensive GPS analysi s package—GAMIT/GLOBK and the precision is good enough to satisfy with the acqu irement of satellite mapping in this area. |
