摘要: 针对我国北斗卫星导航系统(BDS)在南极地区实际应用问题,本文采用精密单点定位技术(PPP)解算了环南极5个跟踪站连续5年的BDS观测数据,分析了环南极BDS PPP定位性能及坐标时序变化。试验结果表明,BDS在环南极卫星星座状态良好,双频PPP水平定位精度优于1 cm,高程定位精度优于1.5 cm,且经过去噪后,X、Y、Z方向坐标变化趋势明显。BDS双频精密单点定位技术可以获取环南极跟踪站高精度连续坐标序列,根据3个方向坐标变化趋势推测周边冰流速和质量的变化,为今后极地冰雪变化研究提供了一种新的技术手段。

Abstract: To address the practical application issues of China's BeiDou Satellite Navigation System(BDS) in the antarctic region.This paper utilizes precise point positioning (PPP) techniques to process BDS observational data from five tracking stations surrounding antarctica over a continuous five-year period,analyzing BDS PPP positioning performance and coordinate time series variations in the antarctic region.The experimental results indicate that the BDS satellite constellation status in the antarctic region is favorable,with dual-frequency PPP horizontal positioning accuracy better than 1 cm and elevation positioning accuracy better than 1.5 cm.After denoising,the trends in coordinate changes in the X,Y,and Z directions are noticeable.BDS dual-frequency precise point positioning technology can obtain high-precision continuous coordinate sequences for antarctic tracking stations.Based on the trends in coordinate changes in three directions,it is possible to infer variations in ice flow velocity and mass in the surrounding area,providing a new technological method for future studies on polar ice and snow changes.

Key words: around Antarctica, BDS, PPP, coordinate temporal sequence
