FIELD: radio engineering, communication.
SUBSTANCE: on-board hardware command and telemetry system of the spacecraft entered the subtraction unit, the compensating signal generator, power module of definition, block of synchronization, block RAM and power generator control signal. In case of interference received command, a distorted hindrance, as is recorded in a block of memory in the module definition block in the pause command signal is detected the presence of the interference signal at a non-zero value of the voltage at the output of the module definition block. As a result, the output determination unit module receives a signal which prohibits transfer of the distorted command signal stored in the memory unit in the instruction decoder.
EFFECT: elimination of distortion control commands sent from the ground control station on board the spacecraft, caused by narrow-band interference.
