Abstract
A payload for a repeater satellite of a communication system. The repeater satellite being placed into drift orbit above the surface of a celestial body. The payload being configured to repeat data received from a stationary satellite above the surface of the celestial body towards a terminal substantially at the surface of the celestial body, and to repeat data received from the terminal towards the stationary satellite. The payload is further configured to use a single frequency band for repeating data towards the stationary satellite, referred to as uplink transmission, and for repeating data towards the terminal, referred to as downlink transmission, as well as to time-division multiplex the uplink transmissions and the downlink transmissions. Also, a telecommunication system includes a repeater satellite provided with aforesaid payload, and a satellite communication method for transferring data between the terminal and the stationary satellite.
