HIGH-SPEED SATELLITE COMMUNICATION SYSTEM INCLUDING AT LEAST ONE POWER SATELLITE PROVIDING ON-BOARD PROCESSING

摘要

A very high speed satellite communication system comprising: - at least one optical earth station (SA); - at least one user satellite (SAT_Util) configured to exchange digital data with user terminals (TU) by a link with radiofrequency signals modulated by said digital data; - at least one power satellite (SAT_Alim_ # i) configured to exchange radio frequency signals with at least one user satellite (SAT_Util) by analog optical link with infrared signals modulated by said radio frequency signals, exchange digital data with at least one station optical earth (SA) by digital modulation optical link, and provided with a modulation / demodulation assembly (Modem); and - at least one terrestrial diversity network (RD).
