摘　　要：为分析北斗卫星导航系统在南极区域数据质量和定位精度,本文以南极拉斯曼丘陵作为研究区域,基于站区常年运行基准站对该区域10个大地控制点进行联测。通过对不同地形、不同天气条件、不同观测时段下的实测数据进行分析,得出了北斗卫星导航定位系统在南极的精度参数,并进行了观测数据质量及定位精度分析。分析结果表明,北斗卫星导航定位系统在拉斯曼丘陵区域的总体精度优于10 mm。In order to analyze the data quality and positioning accuracy of the Beidou satellite navigation system in the Antarctic region.This article takes the Larsemann Hills as the research area,and conducts joint measurements of 10 geodetic control points in the area based on the perennial operating reference stations.Through analysis of measured data under different terrains,weather conditions and observation periods,the accuracy parameters of the Beidou satellite navigation and positioning system in Antarctica are obtained,and the quality of observation data and positioning accuracy are analyzed.The analysis results indicate that the overall accuracy of the Beidou satellite navigation and positioning system in the Larsemann Hills region is better than 10 mm.
