For multipath effects in urban environments with high accuracy single-frequency GNSS receiver, the forecast error handling when considering the ionosphere has been offset error, the ground caused by the propagation environment will be a major factor in system errors. High-resolution channel estimation based on the results of existing cellular communications, the channel response function for extracting the magnitude of wave propagation, phase, Doppler and other features, provided to the L-band signals in a very small error range of linear feature mapping
