An estimation of the spatial-polarization selectivity of GNSS antennas based on analysis of the multipath error from two reflected signals

In this paper, we have estimated the error introduced by the multipath effect in global navigation satellite systems (GNSS) for a stationary user. Based on the mathematical model of the radio path of direct and two reflected signals (multipath model), the results of the multipath error for various types of high-precision positioning antennas are obtained.
