Brief description of the communication between terrestrial stations with the aid of a constellation of satellites

摘要

The invention concerns a method of communication between ground stations via satellites traveling around the Earth and forming part of a constellation overflying at least a major portion of the Earth, each ground station communicating during a particular time with a given satellite of the constellation. Two ground stations communicate via respective given satellites with which the stations are respectively communicating. To minimize the control means on board each satellite, the two satellites communicate via a predetermined communications link. A link of the above kind generally comprises one or more predetermined satellites.
