Accuracy analysis of BDS-3 pseudo-range single-point positioning in the Arctic

摘要: 针对北斗三号卫星导航系统（BDS-3）在北极地区的定位性能,本文基于METG站和SOD3站分析了北极地区BDS-3的卫星可见数、PDOP 值、单频和双频伪距单点定位精度.经研究发现,北极地区BDS-3卫星可见数和 PDOP 值与GPS卫星一致,B1I频率与B3I频率伪距单点定位精度相当,相比于GPS卫星L1频率伪距单点定位精度略差,B1I／B3I频率组合下的伪距单点定位精度低于任一单频伪距单点定位精度,并且相比于GPS卫星L1／L2频率组合下的伪距单点定位精度略差.Abstract: Aiming at the positioning performance of BDS-3 in the Arctic region, based on the METG station and SOD3 station, this paper analyzes the visible satellite number, PDOP value, single-frequency and dual-frequency pseudorange，and single-point positioning accuracy of the BDS-3 in the Arctic region. After research, it was found that the visible number of the BDS-3 satellites and the PDOP value in the Arctic region are consistent with that of the GPS satellites. The pseudo-range accuracy of the single point positioning accuracy of the B1I frequency and the B3I frequency is slightly worse than that L1 frequency of the GPS satellite. The accuracy of the pseudo-range single-point positioning of the B1I／B3I frequency combination is lower than that of pseudo-range single-point positioning of any single-frequency, and is slightly worse than that L1／L2 frequency combination of the GPS satellite.
