In this paper,we study the pseudorange multipath effect of Beidou satellite and analyze the correlation between multipath error and elevation angle ofBeidousatellite.The method of quadratic polynomial fitting and wavelet transform are used to modify the pseudorange multipath.Experiments show that:Quadratic polynomial fitting method to correct the pseudorange multipath error,MP1,MP2 sequence standard deviation of a single satellite maximum reduction of 43.6% and 41.2%;Wavelet transform method to correct the pseudorange multipath error,MP1,MP2 sequence standard deviation of a single satellite maximum reduction of 57.3% and 57.9%.
