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).

[ What is claimed is:] [1.] In a satellite communication system comprising at least one satellite, said at least one satellite being capable of determining a position through reception of external signals, said satellite communication system also comprising at least one ground station, a method for said at least one ground station to direct a narrow antenna beam toward said at least one satellite, said method comprising the steps of:(a) said at least one satellite determining its position through reception of said external signals;(b) said at least one satellite broadcasting, using a low data rate signal, said position through a wide coverage antenna;(c) said at least one ground station directing said narrow antenna beam toward said position in response to said broadcasting step; and(d) said at least one satellite communicating with said at least one ground station using a high bandwidth user information signal communicated between said at least one satellite and said ground station using said narrow antenna beam.
