In order to initially point a directional antenna mounted on a mobile unit to a stationary satellite, the antenna is rotated one revolution in azimuth. While the antenna rotates, the maximum receive signal strength is detected together with the angular position of the antenna at which the maximum strength has been ascertained. Subsequently, the antenna is rotated to the angular position which has been determined in the preceding operation. If the angular position is determined correct (viz., the mobile unit is detected to be synchronized with the satellite), then the initial antenna beam orientation is terminated.
ne antenne directive montée sur une unité mobile est soumise à une rotation azimutale afin de l'orienter vers un satellite stationnaire. Pendant la rotation, l'intensité du signal capté est mesurée et la position angulaire de l'antenne à laquelle cette intensité est maximale est déterminée. L'antenne est ensuite orientée à la position angulaire ainsi déterminée. Si la position angulaire est jugée exacte (c'est-à-dire, si l'unité mobile est en synchronisme avec le satellite), l'opération d'orientation initiale de l'antenne est terminée.
