NON-INTERFERING SATELLITE COMMUNICATION SYSTEM FOR BROAD-BAND COMMUNICATION SERVICES ON BOARD A TRAIN

摘要

The present invention relates to a satellite communication system (30; 30') of a train configured to communicate with a satellite in a given radiofrequency band and to transmit signals to the satellite with a transmission power. The satellite communication system (30; 30') is characterized in that it is also configured to determine a condition of interference indicating the presence of a terrestrial radio- communication system that transmits and/or receives signals in the given radiofrequency band, and to control, as long as said condition of interference persists, the transmission power in such a way that it does not exceed a pre-defined power. The pre-defined power is such that a signal transmitted by the satellite communication system (30; 30') to the satellite with said pre-defined power does not create interference with said terrestrial radio-communication system.
