Abstract
(EN) The invention relates to a method for controlling a transmit antenna (11) of a terminal (1) connected to a ground station (2), the antenna (11) pointing either towards the ground station (2) or towards a satellite (3) configured to relay a signal from the antenna to the ground station (2) along an actual line of sight (15), the method comprising the following steps, which are implemented in an antenna control unit (12) of the terminal (1): - synchronising a time base of the terminal (1) with a time base of a ground station (2), the ground station being configured to be in communication with the terminal (1).
(FR) L’invention concerne un procédé de contrôle d’une antenne (11) d’émission d’un terminal (1) en connecté avec une station sol (3), l’antenne (11 ) pointant soit vers la station sol (3), soit vers un satellite (3) configuré pour relayer un signal issu de l’antenne vers la station sol (3) selon un axe de visée effectif (15), ledit procédé comprenant les étapes suivantes mises en oeuvre dans une unité (12) de contrôle d’antenne du terminal (1) : - synchronisation d’une base de temps du terminal (1) avec une base de temps d’une station sol (2), ladite station sol étant configurée pour être en communication avec le terminal (1).
