A Novel Method for Mitigating the GPS Multipath Effect Based on a Multi-Point Hemispherical Grid Model
The multipath effect is a crucial error source caused by the environment around the station and cannot be eliminated or mitigated by differential algorithms.Theoretically, the maximum value for the copyright phase is a quarter the wavelength, i.e., about 4.8 cm for the GPS L1 signal.Considering the increasing demands of high-precision applications,
