This article is based on the kinematic GNSS observation from the 13th Chinese Arctic Ocean scientific expedition, which marked China's first arrival at the North Pole. It compares and analyzes the observation quality of different signal from BDS and GPS in terms of carrier-to-noise ratio, multipath effects, pseudorange noise, ionospheric delay rate of change, and evaluates their kinematic positioning performance. The results show that the BDS's visible satellite count is still maintained at 8 to 14 close to the North Pole, and that the PDOP value is superior to that of GPS. In the Arctic region, the RMS of multipath combination observation for BDS is around 0.2 m. The RMS of multipath combination observation for B1C and B2a is smaller than the B1Ⅰ and B3Ⅰ signal, but their pseudorange noise is higher. The results of kinematic pseudorange positioning show that the positioning accuracy of BDS is comparable to the GPS, with the B1C/B2a ionosphere-free combination yields better positioning performance than the B1Ⅰ/B3Ⅰ combination.
