Abstract

See full text

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.
