Abstract

A multi-user satellite system provides communication services to external satellites. This satellite system provides in-orbit access points that can be used by the external satellites to offload data instead on relying directly on ground stations. There are a number of advantages that may be achieved by this approach. First, inter- satellite communication between an external satellite and an access satellite of the system may be able to use less complex communication components in the external satellite for radio and/or optical communication than would be required for direct ground-station communication. Furthermore, there may potentially be a greater number of access satellites available than there are available ground stations, and they may provide coverage of more of the used satellite orbits, thereby providing completely avoiding or reducing the need for an external satellite to accumulate data for later offloading.
