ABSTRACT:
A satellite communication system (10) includes apparatus for exchanging communication data between ground-based user sites (21-24, 41-44and51-54) and a ground-based wideband network (60). A communication satellite (30) exchanges user communication data with the user sites. Ground-based hub terminals (27, 35, 47and57) exchange the user communication data with the satellite (30) and also exchange the data with the network (60). A communication manager (70) determines the communication requirements between the satellite and the network and identifies more than one hub terminal to exchange user communication data with the satellite in the event that one hub terminal is insufficient to meet the communication requirements.
