Abstract

Des modes de réalisation d'un procédé, d'un système et de supports pour la prestation de divers services de communication et de divertissement à bord de plateformes qui se déplacent sont donnés à titre d'exemple. Le service peut être proposé entre autres à des satellites de communication sur bande C qui sont placés en orbite géostationnaire et qui couvrent de larges zones de la Terre. Ces services peuvent comprendre notamment les services de transfert de données (par exemple l'accès à Internet), de téléphonie fixe (PSTN et VoIP), de téléphonie mobile (appels et messages), de télécopie, de radiodiffusion, de télédiffusion, de vidéos à la demande (VOD) et d'autres services. L'accès à ces services peut être réalisé, de façon non limitative, par des ordinateurs portables, des ordinateurs personnels, des dispositifs portatifs, des écrans LCD et d'autres dispositifs de visualisation et dispositifs de transmission unidirectionnelle ou bidirectionnelle. Les plateformes qui se déplacent peuvent être des avions, des bateaux de croisière ou des moyens de transport terrestres. Les données du service souhaité sont transmises de la plateforme qui se déplace vers le satellite, et du satellite vers la station terrestre, au moyen d'une antenne pour plusieurs chaînes combinant l'orientation mécanique et éventuellement la commande de phase, et au moyen de dispositifs électroniques associés. Le pointage d'antenne est réalisé grâce à des données de navigation et à des données GPS/GALILEO/GLONASS. La station terrestre peut être reliée simultanément à plusieurs satellites sur bande C. Les données du service sont transmises de la station terrestre aux destinations souhaitées. L'accès aux services de communication à bord des plateformes qui se déplacent est effectué par le biais de la partie frontale du logiciel de facturation qui est intégré à l'interface Web (portail de capture).
