Title (EN) REAL-TIME CALIBRATION OF AN AIR TO GROUND COMMUNICATION SYSTEM
(FR) ÉTALONNAGE EN TEMPS RÉEL D'UN SYSTÈME DE COMMUNICATION AIR-SOL
Abstract: front page image
(EN)A method for real-time calibration of an air to ground two-way communication system. The method includes calibrating a ground base station antenna array according to forward link calibration coefficients received from an aircraft as part of a communication signaling protocol during operation of the air to ground two-way communication system. The method may also includes communicating between the ground base station antenna array and the aircraft over a narrow beam.
(FR)La présente invention concerne un procédé destiné à l'étalonnage en temps réel d'un système de communication air-sol bilatéral. Le procédé comprend l'étalonnage d'un réseau d'antennes de station de base au sol en fonction de coefficients d'étalonnage de liaison avant reçus d'un aéronef, dans le cadre d'un protocole de signalement de communication pendant le fonctionnement du système de communication air-sol bilatéral. Le procédé peut également inclure la communication entre le réseau d'antennes de la station de base au sol et l'aéronef sur un faisceau étroit.
