Abstract

Abstract: In order to clarify the influence of polar environment on the quality of BeiDou satellite data and satellite navigation and positioning services,all the BeiDou satellite observation data acquired in IGS stations and the observations of Zhongshan station are used to analyze the BDS data quality characteristics in the polar region,combined with SNR,multipath error and ionospheric delay rate.The results show that the data of BDS observations in polar stations are more affected by the elevation;the overall signal-to-noise ratio is lower than that of low latitude stations which is comparable to GPS;the multipath effect is more serious;the data from the polar stations are greatly influenced by the ionospheric activities and are different in different time periods.

Key words: BDS, data quality, polar region, multipath, ionospheric delay changing rate
