Methods of Beidou Pseudorange Multipath Deviation Correction
Abstract By analyzing and comparing the MEO satellite pseudorange multipath effect from different satellite system to determine the existence of Beidou satellite pseudorange multipath deviation; further analysis of the BDS three kind of satellite’s pseudorange multipath effect found that IGSO satellite and MEO satellites exist obvious multipath deviation; selecting piecewise linear approximation and piecewise polynomial fitting two methods to build the empirical formula to correct Beidou satellite pseudorange multipath deviation and compared the effects of two methods; by analyzing the characteristics of the MW series and the results of PPP before and after the error correction to demonstrate the effectiveness of empirical formula.
Key words :
Beidou satellite navigation system
pseudorange multipath deviation
