摘要: 针对BDS-3新频率在极地定位的性能问题,本文基于东南极区域4个跟踪站连续多年(2021—2025年)实测数据,分析了BDS-3系统B1C/B2a双频组合PPP精度及每个跟踪站坐标时序变化趋势。试验结果表明,BDS-3在东南极卫星可用性较优,平均可用卫星数为9颗,PDOP值低于3。静态PPP性能较优,水平定位精度优于1 cm,高程定位精度优于1.5 cm。不同跟踪站坐标均有明显的偏移趋势,最大年偏移率达厘米级,主要受当地冰流速和质量变化的影响。同样,也可根据本文研究结果反推冰流速和质量变化,为BDS-3新频率在极地实际应用提供新的参考与依据。

Abstract: Addressing the polar positioning performance of the BDS-3 new frequency,this paper analyzes the B1C/B2a dual-frequency combined precise point position(PPP)accuracy of the BDS-3 system and the coordinate time series variation trend for each tracking station,based on multi-year (2021—2025)measured data from four tracking stations in the East Antarctica region.Experimental results show that BDS-3 offers good satellite availability in East Antarctica,with an average of 9 satellites available and PDOP values below 3.The static PPP performance is excellent,with horizontal positioning accuracy better than 1 cm and vertical positioning accuracy better than 1.5 cm.Each tracking station's coordinates exhibit a significant shift trend,with a maximum annual shift rate reaching the centimeter level,mainly influenced by local ice flow speed and mass changes.Similarly,the study's results can be used to infer ice flow speed and mass changes,providing new references and continuous support for the practical application of BDS-3 new frequency in polar regions.

Key words: East Antarctica, BDS-3, new frequency, PPP
