Использование метода сверхдлинных когерентных накоплений для устранения ошибок многолучевости в приемнике спутниковых радионавигационных систем

Abstract

We propose a method to compensate the errors in pseudo range and Doppler shift measurements resulting from multipath propagation of GNSS signals. The method is based on improving the receiver frequency resolution, which reduces the multi-path effect or even separates a Line of Sight (LOS) signal from a reflected one. Multipath mitigation significantly enhances the positioning accuracy. The method was implemented in a GNSS receiver and tested with GNSS simulator and in real urban canyons
