The Influence of Multipath Propagation of the Signal on the Accuracy of the GNSS Receiver

The GNSS system allows on a planetary scale to fulfill navigation functions, that is, to determine the current location of consumers of navigation information and their speed and to carry out accurate time on the Earth's surface and in near-Earth space. There are several sources of errors that distort the code and the carrier of the navigation signal. The noise floor of the receiver error and the errors from multipath propagation of the signal are independent for each receiver. Multipath propagation of the signal is the main source of errors for high-precision navigation. In this paper we propose a methods for estimation of these errors, which are based on the properties of the time correlation of the multipath propagation of the navigation signal.
