This disclosure provides a communication system using a high-altitude aircraft traveling at relatively slow speeds, which can remain airborne for long periods of time. The communication system uses the airplane as a long term high altitude platform that relays signals between one or more ground-stations and/or satellites, aircraft, and the like. The ground-stations have narrow- beam antennas that are aimable, permitting the aircraft to maintain a larger station than would otherwise be possible using the narrow-beam antennas. The ground-stations adjust their aim based on information either gained by tracking the aircraft's signal, or transmitted by the aircraft to the ground- station.
L'invention porte sur un système de communication utilisant un avion volant à haute altitude et à vitesse relativement faible et pouvant rester en l'air pendant de longues périodes. Ledit système utilise l'avion comme plate-forme relayant des signaux entre une ou plusieurs stations au sol, et/ou des satellites ou d'autres avions ou analogues. Les stations au sol sont munies d'antennes à faisceau étroit directif permettant à l'avion d'évoluer dans une aire plus vaste qu'avec des antennes à faisceau étroit fixes. Les stations au sol dirigent leurs antennes à l'aide d'informations soit obtenues par poursuite des signaux de l'avion, soit transmises de l'avion à la station au sol.
