Identification and mitigation of multipath in GNSS receivers using cluster analysis methods

The paper presents the results of the statistical analysis of the experimental data obtained from GNSS receivers working under multipath conditions. Signal-to-noise ratio and residuals of pseudorange measurements are chosen as investigation parameters. A specific application of the cluster analysis methods for identification and mitigation of multipath is discussed. A technique intended to improve the accuracy of GNSS receivers is suggested. The results of experimental verification of the new method in a static mode are given.
