摘要
针对建设完成后BDS-3在亚太地区双频组合定位性能评估问题,本文基于亚太地区IGS连续跟踪站实测数据,对比分析了BDS-2、BDS-3、BDS-2/BDS-3双频SPP定位精度。研究发现,BDS-3卫星可用性情况和双频组合SPP定位精度优于BDS-2,BDS-2/BDS-3组合卫星可用性情况与双频组合SPP定位精度较任一单系统都有明显提升,X和Y方向定位精度优于0.8 m,Z方向定位精度优于2.2 m。
Aiming at the evaluation of the dual-frequency combined positioning performance of BDS-3 in the Asia-Pacific region after the construction is completed,this paper compares and analyzes the BDS-2,BDS-3,and BDS-2/BDS-3 dual-band frequency SPP positioning accuracy.The study found that the availability of BDS-3 satellites and the dual-frequency combined SPP positioning accuracy are better than BDS-2.The availability of the BDS-2/BDS-3 combined satellites and dual-frequency combined SPP positioning accuracy are significantly improved compared to any single system,X and Y direction positioning accuracy is better than 0.8 m,Z direction positioning accuracy is better than 2.2 m.
