Abstract
Satellite telecommunications system comprises a transmitting/receiving surface terminal associated with a user substantially on a surface of the Earth, a geostationary satellite configured to receive/transmit signals from/to a predefined coverage area with a line of sight to the geostationary satellite, and a traveling satellite moving above the surface of the Earth. The traveling satellite repeats signals received from the surface terminal towards the geostationary satellite and/or repeat signals received from the geostationary satellite towards the surface terminal. The same frequency band is used to communicate between the surface terminal and the traveling satellite and between the traveling satellite and the geostationary satellite. The tracking/telemetry and command signals of the traveling satellite are relayed by the geostationary satellite.
