In order to increase the understanding of the positioning performance of BDS in the polar regions, this paper analyzes PPP (precise point positioning) performance under five different combinations which include BDS-3(B1IB3I), BDS(B1CB2a), BDS(B1IB3I), BDS(B1CB2a+B1CB3I) and GPS(L1L2) using the observation data of 15 IGS (International GNSS Service) stations around the world for 30 days. The results show that the accuracy of the static PPP in polar regions in the three directions of NEU is 1.1 cm, 0.7 cm, and 1.7 cm, and the kinematic PPP accuracy is 10 cm, 9 cm, and 20 cm. The time for static PPP in the polar region to converge to within 10 cm in the three directions of NEU is less than 15 min, 11 min, and 19 min, while the time for kinematic PPP to converge within 20 cm is less than 17 min, 16 min, and 23 min.
