Abstract
In a satellite communication system, a satellite (FIG. 1, 150) determines its position through the reception of global positioning system signals (180). The satellite (150) then broadcasts its position by way of a wide coverage antenna (152) transmitting a low data rate position broadcast (125). A ground station (110) receives the low data rate position broadcast (125) and directs a narrow beam antenna (120) to the reported position of the satellite (150). The ground station (110) then begins high data rate communications with the satellite (150) through the narrow beam antenna (120).
