Cooperative orthogonal multi-satellite communication system
First Claim
1. A satellite communication system comprising:
- a gateway;
a first satellite configured to receive polarized signals from a first plurality of users and orthogonally polarized signals from a second plurality of users;
transmit the polarized signals and the orthogonally polarized signals to the gateway, receive first feeder signals from the gateway, and transmit the first feeder signals to the first plurality of users; and
a second satellite configured to receive polarized signals from the first plurality of users and orthogonally polarized signals from the second plurality of users, transmit the polarized signals and the orthogonally polarized signals to the gateway, receive second feeder signals from the gateway, and transmit the second feeder signals to the second plurality of users.

Abstract
Satellite communication systems and methods are disclosed. The communication system may include a gateway in communication with two satellites. The satellites are configured to receive polarized signals from a first plurality of users and orthogonally polarized signals from a second plurality of users. Each satellite may transmit the polarized signals and the orthogonally polarized signals to the gateway. The first satellite may also receive first feeder signals from the gateway and transmit the first feeder signals to the first plurality of users and the second satellite may also receive second feeder signals from the gateway and transmit the second feeder signals to the second plurality of users.
