Abstract

In a communication satellite system (), communication satellites () that fly on respective orbital planes such as an orbit (A), an orbit (B), and an orbit (C) each include a fore-aft communication device for communicating with other communication satellites () flying in front of and behind that communication satellite (). Each of the communication satellites () flying in each orbit forms cross-link communication with communication satellites () in adjacent orbits at the northern edge of the orbit, indicated by a range (), and the southern edge of the orbit, indicated by a range (), using the fore-aft communication device. Thus, communication between orbits becomes possible only with the fore-aft communication device.
