A method and apparatus useful for determining the accumulated error in a user terminal clock in a satellite communications system. The satellite communications system includes a gateway, a satellite with a known position and known velocity, and a user terminal having a deskew buffer clocked by a user terminal clock. The method includes the steps of computing the one-way signal delay between the satellite and the user terminal, computing a desired deskew buffer delay based on the computed one-way signal delay and a predetermined maximum value of said one-way signal delay, and computing the accumulated error in the user terminal clock based on the desired deskew buffer delay and the actual deskew buffer delay.

L'invention concerne un système et un procédé utiles pour déterminer l'erreur cumulée dans une horloge de terminal utilisateur d'un système de communications par satellite. Ce système de communications par satellite inclut une tête de ligne, un satellite dont la position et la vitesse sont connues, et un terminal utilisateur comportant un tampon de réalignement cadencé par un horloge de terminal utilisateur. Le procédé consiste à calculer le retard du signal unidirectionnel entre le satellite et le terminal utilisateur, à calculer un retard de tampon de réalignement désiré sur la base du retard du signal unidirectionnel calculé et d'une valeur maximale préétablie de ce dernier, et à calculer l'erreur cumulée dans l'horloge du terminal utilisateur sur la base du retard du tampon de réalignement désiré et du retard du tampon de réalignement réel.
