Abstract

This paper considers the possibility of assessing influence of the reflected signal on the parameters of the GNSS signal from the simulator satellite navigation signals Spirent, so that let getting measurements of the selected satellite when exposed only multipath errors. The research was depended of the multipath error of a GPS C/A signal in the presence of one of the reflected signal from the delay of given amplitude of the reflected signal and the comparison of experimental results with theoretical calculations. A result of comparison was revealed that the value of the envelope multipath errors are obtained in the real experiment, in a good agreement with the value of the envelope multipath errors are obtained by the theoretical calculation for the navigation signal receiver. This fact allow to use theoretical calculation at the design stage of a new receiver, in order to assess the influence of multipath errors on the accuracy of the measured navigation parameters at the selected frequency plan and the filter in a high-frequency part of the receiver. The results of field experiments can be used to analyze the ability of the equipment to withstand the multipath errors at a stage of mass production. A theoretical calculation and methodology are in the experimental study are universal and can be used to estimate the multipath error for any GNSS signal.
