摘要：

The multipath of BDS-2 medium earth orbit (MEO) satellites and BDS-3 satellites is analyzed. The multipath bias of BDS-2 satellites is corrected by second order polynomial fitting. By calculating Pearson correlation coefficient between multipath and elevation angle, it is found that the correlation coefficient between multipath and elevation angle of BDS-3 satellites is less than 0.1, and the correlation is not strong. Further, the fourth polynomial fitting model is used to verify that there is no code multipath bias for BDS-3 satellites. By comparing the Root Mean Square (RMS) of BDS-3 satellites code multipath, it is found that the multipath of B1C signal is the largest, approaching 0.5 m, while that of other signals is better than 0.3 m.
