In today\'s world of satellite radio navigation systems are an integral part of human activity. At the same time one of the main factors that reduce the accuracy of current high-performance navigation receivers, is the multipath. The essence of this phenomenon is as follows. Usually at the receiver-s antenna receives not only the direct signal from the navigation spacecraft, and a plurality of multipath signals from the earth\'s surface and surrounding objects. Reflected power can be comparable to the power of the direct signal, which leads to significant distortions of the useful signal and errors in the parameters for tracking circuits of the signal, namely the delay and phase. This article describes a method for substantially reducing the measurement error of the pseudo-code for two-navigation equipme.
