Space-based network architectures for satellite radiotelephone systems
First Claim
1. A space-based network for a satellite radiotelephone system comprising:
- at least one receive-only satellite that is configured to receive wireless communications from a radiotelephone at a predetermined location over a satellite frequency band; and
at least one transmit satellite that is configured to transmit wireless communications to the radiotelephone at the predetermined location over the satellite frequency band;
wherein each of the receive-only satellites comprises first and second receive antennas; and
wherein each of the receive-only satellites further comprises first through fourth processors, the first processor being configured to process wireless communications that are received by the first receive-only antenna in a first polarization, the second processor being configured to process wireless communications that are received by the first receive-only antenna in a second polarization, the third processor being configured to process wireless communications that are received by the second receive-only antenna in the first polarization and the fourth processor being configured to process wireless communications that are received by the second receive-only antenna in the second polarization.

Abstract
A space-based network for a satellite radiotelephone system includes at least one receive-only satellite and at least one transmit satellite. The transmit satellite can be a transmit-only satellite or a transmit and receive satellite. The receive-only satellite(s) are configured to receive wireless communications from a radiotelephone at a location over a satellite frequency band. The transmit satellite(s) are configured to transmit wireless communications to the radiotelephone at the location over the satellite frequency band. By providing at least one receive-only satellite and at least one transmit satellite, space-based networks can offer a significant link margin, without the need to undesirably burden the radiotelephones themselves to achieve this link margin.
