RADIO INTERFERENCE CANCELLER FOR PROVIDING ELECTROMAGNETIC COMPATIBILITY OF LOCAL GNSS CONSUMER NAVIGATION EQUIPMENT WITH LOCAL MEANS FOR RADIO SUPPRESSION OF ENEMY CONSUMER NAVIGATION EQUIPMENT WHEN OPERATING AT SAME FREQUENCIES Russian patent published in 2015 - IPC G01S7/36 

FIELD: radio engineering, communication.

SUBSTANCE: method is carried out by cancelling radio interference in local radio equipment using information concealed from the enemy on the fine structure of the interference signal and inability to cancel radio interference in the radio equipment of the enemy in the absence of concealed information. The radio interference canceller is placed between an antenna amplifier and the receiver of consumer navigation equipment and consists of a downmixer, an intermediate frequency amplifier, a harmonic signal mixer, a local heterodyne, a multiplier, a phase-lock loop, an automatic delay tracking circuit, a circuit for selecting and storing compensated voltage pulse envelopes, an automatic signal amplitude tracking circuit, a compensated voltage instance generator, a subtractor and a restoring mixer, made and connected to each other in a certain manner.

EFFECT: providing electromagnetic compatibility of local consumer navigation equipment of global navigation satellite systems with local radio interference transmitters without reducing the efficiency of radio suppression of consumer navigation equipment of global navigation satellite systems of the enemy.
