摘要：

为了给中国南极野外考察队提供DEM卫星影像图,在2002/2003年南极度夏期间,中国第19次南极考察队的大地测量工作者,在东南极Grove山地区,进行了地面控制测量。在覆盖面积达8000km~2的2000多米高的内陆冰盖高原区,在直升机和雪地车的支持下,利用Trim- ble4000ssi GPS接收机,与中山站GPS跟踪站联测,测量了7个GPS控制点,并埋设了永久性测量标志。数据处理采用GAMIT/GLOBK软件解算,获得了较好的定位精度,能够满足该地区制图所需。

Abstract:

During 2002/2003 austral summer season,the 19th Chinese National Antarctic Research Expedition(CHINARE)carried out the 3rd expedition in Grove Mountains,East Antarctica. The extension is 72°20′to 73°12′S,73°40′to 75°50′E and covers approximately 8000km~2. Seven Geodetic control points were set up with the support of helicopter and over-snow vehicles using duel frequency GPS receivers.GAMIT/GLOBK,a comprehensive GPS analysis paekage was used to process the GPS,data.The results show the precision is good enough to satisfy the acquirement of mapping from the satellite image map in Grove Mountains.
