Title (EN) A SIGNALING AND RANGING TECHNIQUE FOR A TDMA SATELLITE COMMUNICATION SYSTEM
(FR) TECHNIQUE DE SIGNALISATION ET DE TELEMETRIE POUR UN SYSTEME DE COMMUNICATION A SATELLITE TDMA
Abstract: front page image
(EN)Technique for creating dedicated in-band, two-way, signaling channels between a master signaling ground station and each remote ground station of a satellite communication system using either an area coverage beam or a plurality of fixed and/or scanning spot beams. In the present technique, separate bursts of information within a superframe sequence are dedicated for only providing signaling information between the master signaling station and each ground station of the system. Each ground station, in turn, is dedicated a separate burst of information for transmitting only signaling information back to the master signaling station. Coarse ranging is performed by triangulation methods and then each ground station transmits a unique word within the predetermined time period of its dedicated signaling burst to the master signaling station. The master signaling station then transmits synchronization correction information back to each ground station in its dedicated signaling burst.
(FR)Technique de creation de canaux de signalisation en bande, a deux voies, entre une station mere terrestre de signalisation et chaque station terrestre eloignee d"un systeme de communication par satellite utilisant soit un faisceau de couverture de zone soit une pluralite de faisceaux fixes et/ou de faisceaux a exploration fixe. Dans la presente technique, des chaines fermees separees de donnees d"information dans une sequence de super repartiteur sont consacrees seulement pour envoyer des signaux d"informations entre la station mere de signalisation et chaque station terrestre du systeme. Chaque station de terre, a son tour, recoit une chaine fermee separee de donnees d"informations pour transmettre en retour seulement une information de signalisation a la station de signalisation mere. Une telemetrie grossiere est effectuee par des methodes de triangulation puis chaque station de terre transmet un mot unique dans la periode de temps predeterminee de sa chaine fermee de donnees de signalisation a la station mere de signalisation. La station mere de signalisation renvoie alors une information de correction de synchronisation a chaque station terrestre dans sa chaine fermee de donnees de signalisation consacree.
