ABSTRACT:
For exchange of information between an earth-station and a satellite in geostationary orbit, information signals addressed to the satellite are transmitted from the earth-station, and information signals from the satellite are received at the earth-station. Signals addressed to the satellite and the signals from the satellite have a common first carrier frequency. Signals addressed to the satellite are transmitted to an intermediate satellite with an angular offset from the satellite in geostationary orbit. The intermediate satellite retransmits signals laterally to the geostationary orbit satellite on a second carrier frequency different from the first carrier frequency.
