摘要：

本文论述了南极长城站地区卫星多普勒定位的数据处理工作。简要介绍定位的数学模型,并着重分析了南极地区卫星多普勒定位的结果。通过对预处理、仪器频漂、单点定位、联测定位、解的收敛状态以及广播星历误差等方面的分析,作者认为在南极地区利用卫星多普勒定位技术进行高精度大地测量或冰川运动监测等都是一种有效的定位手段。最后给出了一些有关数据与结论。

Abstract:

In this paper the data processing of satellite Doppler Positioning of Antarctic Great Wall Station region is descibed. After brieqf a positioning mathematical model, the positioning results and accuracy analysis are given. Analyzing the results of pre-proces-sing,receiver drift, point positioning and translocation, the covergence of solutions and the errors of broadcast ephemeris, the authors believe that satellite Doppler positioning an useful means applied to precise geodetic positioning and monitoring glaeier motion in Antarctic region.
