FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used in receivers of global navigation satellite systems using broadband signals phase-manipulated with pseudorandom sequence. Navigation receiver with interference compensator on its input receives a mixture of a navigation signal and signal-like noise emitted by local means for electronic countermeasures located within radio coverage of global navigation satellite system receiver. In channel for generation of noise instance, noise detector is a signal detector with known parameters and unknown delay time and configured to detect only signal-like noise. In channel for generating noise instance, method includes reproduction of noise instance, synchronous in time delay with detected signal-like noise, followed by subtraction of generated noise instance from input mixture of navigation signal and signa-like noise.
EFFECT: technical result of invention is to improve noise immunity of reception of navigation signals by reproducing instances of signal-like noise based on delay time and subsequent compensation of interference from input signal-noise mixture.
