FIELD: automatic adaptive high frequency packet radio communications. ^ SUBSTANCE: each high frequency ground station contains at least one additional high frequency receiver for "surface to surface" communication and at least one additional "surface to surface" demodulator of one-tone multi-positional phase-manipulated signal, output of which is connected to additional information input of high frequency controller of ground station, and input is connected to output of additional high frequency "surface to surface" receiver, information input of which is connected to common high frequency receiving antenna, while control input is connected to additional control output of high frequency controller of ground station. ^ EFFECT: prevented disconnection from "air to surface" data exchange system of technically operable high frequency ground stations which became inaccessible for ground communications sub-system for due to various reasons, and also provision of possible connection to high frequency "air to surface" data exchange system of high frequency ground stations, having no access to ground communication network due to absence of ground communication infrastructure at remote locations, where these high frequency ground stations are positioned. ^ 2 cl, 12 dwg, 2 tbl |
