Abstract

L'invention porte sur un appareil (10) d'un système robuste de poursuite d'antenne qui est capable de poursuivre rapidement et avec précision des satellites sans utiliser de compas, dans des conditions défavorables, tout en étant soumis à une grande contrainte de couple et en étant à l'abri des intempéries. L'appareil peut être relié à un bateau ou à un véhicule terrestre, et peut être utilisé lorsque le véhicule se déplace. Lorsque le client choisit un satellite à partir duquel il reçoit des signaux (202), l'invention acquiert un satellite primaire (204) marqué par le système. L'identification du satellite primaire marqué par le système est réalisée en comparant les bords avant et descendant de l'impulsion (220a) du signal RF, en comparant les transmissions (220b) de signaux de radiophare, en comparant le positionnement relatif d'autres satellites (220c), ou en déterminant l'angle d'élévation du satellite par rapport à l'horizon (220d). Lors de l'identification du satellite primaire marqué par le système, le satellite choisi par le client est localisé en calculant sa position par rapport au satellite primaire (300, 302) marqué par le système, puis en vérifiant (306) le satellite choisi par le client par l'intermédiaire des quatre moyens d'identification utilisés pour le satellite primaire (220a, 220b, 220c et 220d) marqué par le système. Les satellites sont poursuivis en mesurant l'augmentation et la diminution de l'intensité (308, 310a et 310b) du signal au moment où l'antenne est déplacée sur une distance connue dans la plage de satellites.
