Title (EN) HIGH DATA RATE AIRCRAFT TO GROUND COMMUNICATION ANTENNA SYSTEM
(FR) SYSTÈME D'ANTENNE DE COMMUNICATION AVION-SOL À DÉBIT DE DONNÉES ÉLEVÉ
Abstract: front page image
(EN)A method for ground to air communication includes receiving a first pilot signal on a first wide beam from a first ground base station by a first antenna element covering a first range of azimuth angles from an aircraft. Data is received on a directed data beam from the first ground base station by the first antenna element. A second pilot signal is received on a second wide beam from a second ground base station by a second antenna element covering a second range of azimuth angles different than the first range of azimuth angles. A signal strength of the second pilot signal is compared with a signal strength of the first pilot signal. Data reception is switched from the first antenna element to the second antenna element if the signal strength of the second pilot signal is greater than the signal strength of the first pilot signal.
(FR)L'invention porte sur un procédé de communication sol-air qui consiste à recevoir un premier signal pilote, sur un premier faisceau large, d'une première station de base terrestre, par un premier élément d'antenne couvrant une première plage d'angles d'azimut à partir d'un avion. Les données sont reçues, sur un faisceau de données orienté, de la première station de base terrestre par le premier élément d'antenne. Un second signal pilote est reçu, sur un second faisceau large, d'une seconde station de base terrestre, par un second élément d'antenne couvrant une seconde plage d'angles d'azimut différente de la première plage d'angles d'azimut. Une intensité de signal du second signal pilote est comparée à une intensité de signal du premier signal pilote. La réception de données est commutée du premier élément d'antenne au second élément d'antenne si l'intensité de signal du second signal pilote est supérieure à l'intensité de signal du premier signal pilote.
