FIELD: radio equipment.
SUBSTANCE: invention relates to radio engineering, in particular to the field of compensation for deliberate radio interference with known structure and parameters in the navigation user equipment of the global navigation satellite system. Timing unit is entered into the compensation device, and a signal analyzer, a second generator of a copy of intentional radio interference, the first and second matched filters are added to each compensator included in the compensation device, the input of the compensator is connected to the input of the first matched filter and to one of the inputs of the subtractor, the output of the first matched filter is connected to one of the inputs of the signal analyzer, the input of the first generator of the copy of the intentional radio interference is connected to the output of the timing unit, the output of the first generator of copies of intentional radio interference is connected to the input of the second matched filter, the output of which is connected to another input of the signal analyzer, one of the outputs of the signal analyzer is connected to the input of the second generator of the copy of intentional radio interference, another output of the signal analyzer is connected to the input of the control attenuator, the output of the second generator of the copy of the intentional radio interference is connected to one of the inputs of the controlled attenuator, the output of which is connected to another input of the subtracting device, the output of the subtracting device is the output of the compensator, the device allows in each compensator to form a copy of the radio interference created by a particular radio interference station, analyze and compensate for radio interference with a known structure and parameters created by radio interference stations by subtracting a copy of the intentional radio interference from the input signal.
EFFECT: increasing the efficiency of compensation for intentional radio interference with known structure and parameters.
