FIELD: satellite radio navigation.
SUBSTANCE: proposed receiver that can be used on mobile equipment such as cash messenger vehicles for primary processing of information arriving from two mistuned satellite radio navigation systems "NAVSTAR" and "GLONASS" has antenna, input feeder, broadband preselector filter, first keying amplifier, first band filter, second low-noise amplifier, first mixer, frequency synthesizer, standard temperature-controlled generator, second band filter, first intermediate-frequency amplifier, complex frequency conversion unit, automatic gain control unit, second mixer, third band filter, second intermediate-frequency amplifier, correlator, threshold unit, and switch. Receiver incorporates provision for suppressing spurious signals (noise) received from image and combinatorial channels.
EFFECT: enhanced selectivity and noise immunity of receiver.
