  • Combined navigation and mobile communication satellite architecture
    Patent number: 6311128
    Abstract: A navigation and mobile communication satellite system including a Geo-Mobile (GEM) satellite (14) and a plurality of Global Position System (GPS) satellites (50). The GEM satellite (14) is in operative communication with at least one ground segment (12) and at least one user segment (16), and includes a GEM processor for providing communication services to the user segments (16). The GPS network is also in operative communication with at least one of the user segments (16) and at least one of the ground segments (12). The GPS network provides navigation data to the user segment (16). Each of the ground segments (12) include a gateway station (28) for receiving the navigation data and uplinking the navigation data to the GEM satellite (14) such that the navigation data is rebroadcast to the user segments (16) at a higher power than from the GPS network alone. In this manner, the GEM system provides a navigation signal at a much higher power than the present GPS system.
