NETWORK AND METHOD FOR CALCULATING IONOSPHERE CORRECTIONS Russian patent published in 2013 - IPC G01S19/07 

FIELD: radio engineering, communication.

SUBSTANCE: network comprises an aeronautical segment (200) having an aeronautical user segment composed of a plurality of aircraft (2) having on-board radio-frequency receivers (21) capable of measuring delays of the navigation signals transmitted by the satellites (GNSS) and an aeronautical data communication means (5) between the plurality of aircraft (2) and the ground segment (300) in order to transmit measurements to the ground segment (300), and means, at the level of the ground segment (300), of receiving measurements used for calculating said grid, the measurements of delays coming from the plurality of aircraft (2) and from the plurality of ground stations (SBAS G).

EFFECT: high reliability in the communication structure of ionosphere corrections using existing aircraft communication lines directed towards a ground segment, high accuracy of corrections, enabling detection of small ionosphere perturbations, eliminating constraints for coverage of sea areas or mountain areas.
