FIELD: communication.
SUBSTANCE: invention relates to systems for transmitting digital information over a low-directivity optical laser communication channel with an aircraft to a data collection station constructed using optical information quantum reception technology. Essence of the disclosed solution lies in the fact that a method and a system for transmitting media information from aircraft to a data collection point on a low-directivity optical channel with a quantum reception of a media stream is that when an input signal containing streaming video information is transmitted to a transmitter mounted on an unmanned aerial vehicle or spacecraft, the signal is encrypted, encoded with a Reed-Solomon code correcting errors, packing Ethernet frames, generating pulses, transmission of pulses by means of a laser to a receiver mounted on the Earth or other carrier, where the obtained pulses, when falling on the photosensitive surface of the multisection matrix, form a spot of several millimeters, after which the sequence of frames in time is analyzed and compared with the threshold operation coefficient of the system to determine random noise with intensity below the trigger threshold, dropping the frame with random noise, further, Ethernet frames are decompressed, Reed-Solomon code is decoded and decrypted, then information is sent to computer.
EFFECT: technical result consists in provision of possibility of use both with stationary (ground stations, tower operators of cellular network, et cetera), and mobile carriers (satellites, airplanes, airships, trains, cars, helicopters, unmanned aerial vehicles).
