Abstract
A communication system comprising a set of non-geostationary satellites provides communication links between ground stations and terminals, a communication link from a particular station via a satellite terminating at associated terminals in a limited geographical area including the station and providing a communication channel to at least some of the associated terminals. The communication link is switched to another satellite during the process of communication link handover. A communication link between a particular station and its associated terminals includes an additional communication channel which enables advance data to be transmitted between the particular station and a terminal before the latter executes a communication link handover. This data masks any interruption of communication caused by the communication link handover.
