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.

基于我国首次到达北极点的第13次北冰洋科考动态GNSS观测数据,从载噪比、多路径效应、伪距噪声、电离层延迟变化率等方面对比分析了BDS和GPS不同频率的观测量特性,并评估其动态定位性能。结果表明,在北极点附近BDS的卫星可见数仍保持在8~14颗,PDOP值优于GPS;北极地区BDS多路径组合观测量RMS在0.2 m左右,B1C和B2a信号多路径组合观测量RMS较小,但其伪距噪声大于B1Ⅰ和B3Ⅰ信号;动态伪距定位结果表明,BDS定位精度与GPS相当,其中B1C/B2a信号无电离层组合的定位性能优于B1Ⅰ/B3Ⅰ信号无电离层组合。
