Abstract

L'invention concerne des systèmes et des procédés permettant d'utiliser des configurations de liaison de connexion destinées à supporter une modulation en couches. Un premier système de liaison de connexion permet d'utiliser un faisceau de points de liaison de connexion avec des antennes dans des zones de couverture distinctes afin de permettre la réutilisation d'une fréquence. Un deuxième système utilise une antenne à liaison de connexion à faisceau étroit afin d'éclairer des satellites individuels, ce qui permet également de réutiliser une fréquence. Un troisième système utilise une modulation en couches dans la liaison de connexion. Un dernier système de liaison de connexion utilise une modulation synchrone d'ordre plus élevé que celle utilisée dans les signaux de liaison descendante à modulation en couches pour une liaison de connexion de satellite.
