The signals always form the reflection over the sea. The characteristics and correct method of the multipath over the sea are worthy of research. Based on the assumption that the high-precision posterior residual only contains multipath error and noise, this paper adopts forward and backward filtering estimation and PPP-AR strategy to obtain the high-precision observational post-residual and then calculates the multipath error effect based on the mean denoising method. The azimuth and elevation angle mapping relationship of the azimuth angle and elevation angle are constructed, the station center multipath hemispherical map (MHM) is constructed, and the different grid resolutions of MHM are experimentally studied. The experimental results show that the MHM model can effectively improve the positioning effect of the marine buoy rather than no multipath correction. Not only the positioning accuracy can be improved, but the ambiguity fixed-rate and convergence time of positioning can also be improved, especially the 2° × 2° resolution of the MHM model has good results in both static and dynamic scenarios.
