METHOD AND SYSTEM OF BLOCKING UNAUTHORIZED CHANNEL OF INFORMATION TRANSMISSION FROM EARTH BASED RADIO TRANSMITTER TO SPACECRAFT Russian patent published in 2018 - IPC H04K3/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the field of radio engineering and can be used to provide blocking of "Earth station (ES) – spacecraft (SC)" space radio links (SRL). For blocking an unauthorized transmission channel use AC (aircraft), whose position in space is maintained in such a way, so that it is in the zone of direct radio visibility from the earth station or from a fixed point in the vicinity of the disposition of several ESs to the spacecraft. AC has radio receiving and radio transmitting devices on board, the orientation of the radiation patterns is maintained during the flight, for the radio receiver – to the location of the ES, and for the radio transmitter – in the direction of the SC.

EFFECT: technical result consists in the possibility of detecting in real time the parameters of the signals of an unauthorized SRL from one or several terrestrial transmitters in a fixed area of their dislocation to the SC on-board satellite receiver and use them to generate and transmit an interference signal from the aircraft (AC) board.
