mobile satellitenkommunikationsanordnung, several earth stations using

摘要

Satellites (100a,100b) provide good coverage of mobile terminal service regions and ground stations (200) can communicate with all satellites if there is an unobstructed view. The ground stations allow a mobile terminal to be connected to a network as near as possible to the other party and feeder link antennas (201) are oriented towards the satellites for transmitting feeder link signals to the satellites in the up-link frequency band. Independent claims are included for a method for communicating between plural satellites and for a method of transmitting signals from a ground station to a satellite.
