HIGH-FREQUENCY DATA EXCHANGE SYSTEM Russian patent published in 2019 - IPC H04W40/00 H04L12/701 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to automatic adaptive high-frequency packet radio communication. To achieve a technical result, (n+m+1) high-frequency ground station is introduced, connected by two-way connections to corresponding inputs/outputs of control center and HF radio channels "Earth-Earth" to those HF ground stations, which are in the zone of stable communication single-jump track, as well as high-frequency ground stations according to the number of air traffic control centers and air lines, connected to them by two-way communications and over high-frequency radio channels "Earth-Earth" to those high-frequency ground stations, which are in the zone of stable connection of single-hop route.

EFFECT: broader functional capabilities of the system, specifically selecting an optimum radio channel and operating frequency for a single-hop route, an optimum route, establishment of communication with the required subscriber due to bypassing of the failed ground communication subsystem by means of high-frequency ground stations, available high-frequency on-board stations and transmission of messages between the system objects via the corresponding high-frequency radio channels and prompt correction of message delivery traffic to the corresponding subscriber in case of failure of high-frequency radio channels assigned by the control center.
