FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. An apparatus for receiving navigation signals comprises a first correlator configured to correlate a first channel with a first code to provide a first output signal, wherein the first channel has a carrier frequency and data, and a second correlator configured to correlate a second channel with a second code to provide a second output signal, wherein the second code is different from the first code, and the second channel has the same carrier frequency as the first channel and the same data as the first channel.
EFFECT: high transmission reliability.
