Hybrid space system based on a constellation of low-orbit satellites working as space repeaters for improving the transmission and reception of geostationary signals
First Claim
1. Satellite telecommunications system, comprising:
- at least one transmitting/receiving surface terminal associated with a user substantially on a surface of the Earth;
at least one geostationary satellite configured to receive signals from and to transmit signals to a predefined coverage area with a line of sight to said at least geostationary satellite, andat least one traveling satellite moving above the surface of the Earth and configured to perform at least one of the following using a same frequency band;
repeat signals received from said at least one transmitting/receiving surface terminal towards said at least one geostationary satellite, or repeat signals received from said at least one geostationary satellite towards said at least one transmitting/receiving surface terminal, the same frequency band is used to communicate between said at least one transmitting/receiving surface terminal and said at least one traveling satellite and between said at least one traveling satellite and said least one geostationary satellite; and
wherein tracking/telemetry and command signals of said at least one traveling satellite are relayed by said at least one geostationary satellite.

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.
