    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.
