Abstract

Un système de satellites comprend au moins deux satellites ayant à bord des installations de traitement qui permettent l'échange de messages de données et la détermination de la position d'unités mobiles avec un accès direct depuis des installations multiples de commande au sol. Les satellites transmettent des données et interrogent des unités mobiles individuelles selon des instructions reçues d'une ou plusieurs installations de commande et reçoivent des réponses des unités mobiles, y compris leur altitude et d'autres données d'intérêt pour l'installation de comande. Au moins deux satellites communiquent l'un avec l'autre par une voie de communication croisée. Les satellites comprennent des appareils de traitement par ordinateur pour calculer les distances entre les unités mobiles et chaque satellite sur la base des réponses reçues des unités mobiles, pour enregistrer et traiter des messages. Les informations concernant la position et les messages sont transmises à au moins une des installations de commande. De préférence les installations de commande utilisent des protocoles d'accès multiple par partage dans le temps (TDMA) ou d'accès multiple par partage des fréquences (FDMA) pour communiquer avec les satellites. Le traitement à bord permet aisément à une pluralité d'installations de commande d'avoir directement accès aux statellites plutôt que de passer par une station centrale au sol et d'augmenter la capacité d'un système d'interrogation d'adresses individuelles sur un spectre donné de fréquences radio attribuées. Un système d'interrogation d'adresses individuelles est un système dans lequel chaque unité mobile est individuellement interrogée et répond seulement à des interrogations qui l'identifient expressément.
