Abstract:
Characteristics of different GPS, GLONASS, Galileo, COMPASS, QZSS signals are resulted. The model of an inpute signal with the account of the reflected signals (multipath) is considered. The model of pseudo-noise signals takes into account features of of Gold codes. The algorithm of calculation of a multipath error on the basis of the decision of the equations with using correlation of components I, Q, dI, dQ the receiver correlator is resulted. Multipath error estimation for real signal with Gold-s codes, and also multipath error comparison for BPSK-signals and BOC-signals is resulted. Influence of Gold codes on a multipath error is shown
