FIELD: electrical communication engineering.
SUBSTANCE: invention relates to data transmission and can be used in wireless communication systems. Method comprises steps of receiving a first radio navigation signal from at least one of a plurality of transmitters and obtaining therefrom a first OCM signal SA, and receiving second signal SB, synchronously broadcast with the first OCM signal SA, wherein second signal SB has same or adjacent center frequency relative to first OCM-signal SA. Method further comprises generating a combined value YC correlation, wherein combined value YC correlation corresponds to correlation of combined signal SC with replication of first OCM-signal and combined signal Sc is obtained as a result of coherent combination at receiver of first OCM-signal SA with second signal SB. Method further comprises acquiring range information based on a combined value of YC correlation. Second signal SB can contain (i) an OCM signal or (ii) a BOC signal. Combination of two signal components can be performed before or after correlation operation. When such technology is received by a range receiver, it offers improved characteristics in the area of signal capture and repeated signal capture for tracking, in particular, reducing the probability of capture on by-peaks; accurate capture and tracking: reduced or eliminated probability of false code capture.
EFFECT: technical result consists in improvement of noise immunity of data transmission.
