Characteristics analysis and elimination strategies of multipath error for BDS

WANG Jianjun;MA Xuying;Land and Resources Surveying Institute of Qingyuan;Tongji University;  
In order to eliminate the multipath errors which affect the high-precise navigation service performances of BDS,the paper extracted the multipath errors of several stations and analyzed their characteristics,and discussed the multipath error elimination strategies in different positioning resolution ways.Results showed that the accuracy of single point positioning would be improved largely compared with the original solution after removing the multipath errors,the sidereal filtering based on periods of BeiDou multipath errors would partly eliminate the period errors related to satellite-receiver geometry,and the accuracy of relative positioning for short baselines would be significantly enhanced,which could provide a reference for the processing of BDS data.
