Abstract
A satellite communication system architecture that supports both commercial and tactical applications may include polarization-based multiplexing and de-multiplexing and common routing. Such a satellite may be placed in such a way as to minimize intentional interference.
Claims36
A satellite communication payload comprising:
- an uplink polarization separation module to separate received signals of different polarizations into separate signals;
- a routing module coupled to said uplink polarization separation module to route said separate signals to signals for downlink processing;
- and
- a downlink polarization module to combine said signals for downlink processing into transmitted signals using a different polarization for each of said signals for downlink processing.

A method of communicating tactical and non-tactical signals using a single-hop satellite communication system, comprising:
- receiving uplink signals comprising tactical signals transmitted using a first polarization and non-tactical signals transmitted using a second polarization;
- separating said tactical signals and said non-tactical signals based on their respective polarizations;
- routing said tactical and non-tactical signals, using a common satellite-based router, into downlink tactical signals and downlink non-tactical signals;
- combining said downlink tactical signals and said downlink non-tactical signals into downlink signals by polarizing said downlink tactical signals using a third polarization and polarizing said downlink non-tactical signals using a fourth polarization.
