Abstract:We provide a validation method of multipath model of BDS-3 new frequencies. We use antenna group delay test and measured data to verify the multipath error characteristics of BDS meet the requirements of DFMC multipath model. The results show that: 1) The receving antenna used in the experiment meet the requirements of DO-373. 2) In the case of B1c/L1, B2a/L5 and dual-frequency combination, the trend of multipath error curve of BDS and GPS are basically the same; that is, the characteristics of multipath error of BDS and GPS are basically the same. 3) The multipath error characteristics of BDS in the case of B1c, B2a and dual-frequency combination can meet the requirements of the DFMC multipath model.
