A system and method for carrying out a hand-off of a satellite-based communications link with a mobile platform, such as an aircraft, leaving a first coverage region and entering a second coverage region. A land-based communications link connects ground stations in each of the coverage regions for communications with one another and also with a network operations center (NOC). As the aircraft enters an area of overlap between the two coverage regions, a sequence of communications is initiated between the ground stations and also between each of the ground stations and the aircraft to ensure that new forward link and return link assignments are received by the aircraft before the aircraft relinquishes its communications link with the first ground station to begin communicating with the second ground station. The hand-off in communications is accomplished in less than approximately 30 seconds of time after one of the ground stations detects that the aircraft has entered a pre- defined overlap area between the two coverage regions.

L'invention concerne un système et un procédé permettant de réaliser un transfert de liaison de communication par satellite avec une plate-forme mobile, telle qu'un aéronef, sortant d'une première zone de couverture et entrant dans une deuxième zone de couverture. Une liaison de communication terrestre connecte des stations terrestres dans chaque zone de couverture pour qu'elles communiquent entre elles et également avec une centre d'exploitation de réseau (NOC). A mesure que l'aéronef entre dans la zone de chevauchement entre les deux zones de couverture, une séquence de communication est lancée entre les stations terrestres et également entre chaque station terrestre et l'aéronef pour assurer la réception par l'aéronef de nouvelles attributions de liaison aller et de liaison retour, avant que ce dernier abandonne sa liaison de communication avec la première station terrestre pour commencer à communiquer avec la deuxième station terrestre. Le transfert de communication est réalisé en un temps inférieur à environ 30 secondes après qu'une des stations terrestres a détecté l'entrée de l'aéronef dans une zone de chevauchement prédéterminée entre les deux zones de couverture.
