SATELLITE CONTROL CHANNELS RADIO SUPPRESSION METHOD Russian patent published in 2019 - IPC H04K3/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the communication technology, in particular for the artificial radio interference creation, and can be used for radio suppression (RS) of the satellite command-program radio links (CPRL), operating according to the CCSDS standards. For the satellite control channels radio suppression, receiving the radiation source signals in all operation sub-bands of Δf₁, Δf₂ … Δf_i, identifying the detected signal as the “spacecraft-to-Earth” (“SC-Earth”) control channels (CC) signal, determining and memorizing the “Earth-SC” CC frequency value, generating the control signals by the transmission mode and emitting the interfering signal at the frequency, corresponding to the “Earth-SC” CC previously stored frequency. Evaluating the CC RS efficiency, for which re-receiving the of the radiation source signal at the “SC-Earth” CC frequency, and recording the information presence therein, transmitted for the purpose of the telecommands handshaking from the ground control station. If this information takes place, then successively increasing the interfering signal effective isotropically radiated power until the transmission of acknowledgments of the telecommands reception on the “SC-Earth” CC frequency is ceased.

EFFECT: technical result of the invention consists in the development of the satellite CC RS method, providing the satellite CC RS with previously unknown operating frequencies and the RS efficiency objective monitoring during jamming.
