Method and apparatus for simultaneous live television and data services using single beam antennas
First Claim
1. A system for simultaneously receiving on a mobile platform first RF signals having a first polarization from a first satellite at an orbital location and second RF signals having a second polarization from a second satellite that is substantially co-located at the orbital location with the first satellite, the system comprising:
- a single beam receive antenna aperture arranged to receive first RF signals having a first polarization and second RF signals having a second polarization, the single beam receive antenna aperture outputting output signals having the first polarization;
a first RF converter arranged to down-convert the output signals to first down-converted signals having the first polarization; and
a second RF converter arranged to down-convert the output signals to second down-converted signals having the second polarization.

Abstract
A method and apparatus are provided for simultaneously receiving DBS and data signals on a mobile platform using a single beam receive antenna aperture and transmitting data signals from a mobile platform using the single beam transmit antenna aperture. A single beam receive antenna aperture receives first RF signals having a first polarization and second RF signals having a second polarization, the single beam receive antenna aperture outputting output signals having the first polarization. A first RF converter down-converts the output signals to first down-converted signals having the first polarization. A second RF converter down-converts the output signals to second down-converted signals having the second polarization. The first RF signals suitably include DBS signals, and the second RF signals suitably include data services signals.
