Placement of gateways near service beams
DCFirst Claim
1. A spot beam satellite comprising:
- an antenna system configured to create a beam pattern having a plurality of different colors, wherein a color has a unique combination of frequency band and polarization, the spot beam satellite being configured to receive data from a plurality of service beams and from at least one feeder beam, each service beam having an associated service beam coverage area and the at least one feeder beam having an associated feeder beam coverage area,wherein the feeder beam coverage area is proximate to one or more of the service beam coverage areas,wherein the at least one feeder beam and a service beam associated with each of the one or more service beam coverage areas proximate to the feeder beam coverage area are allocated different colors from the beam pattern, such that signals associated with different colors differ by a frequency band, a polarization, or both a frequency band and a polarization,wherein the feeder beam coverage area is not proximate to one or more of the service beam coverage areas, andwherein a set of colors allocated to a service beam associated with each of the one or more service beam coverage areas not proximate to the feeder beam coverage area includes at least one same color allocated to the at least one feeder beam, such that signals associated with the same color have the same frequency band and polarization.

Abstract
A method and system are presented for operating a multibeam satellite system involving positioning a plurality of service beams associated with a plurality of service beam coverage areas and positioning a feeder beam associated with a feeder beam coverage area. The feeder beam coverage area is at a proximity to at least one service beam coverage area. The feeder beam coverage area includes at least one gateway. Each of the plurality of service beam coverage areas uses a color. The at least near service beam coverage area uses at least one color from the plurality of colors. The feeder beam uses at least one color, excluding the at least one color used by the at least one near service beam coverage area.

13. A method of operating a spot beam satellite, the method comprising:
-
receiving data at the spot beam satellite from a plurality of service beams and at least one feeder beam, each service beam having an associated service beam coverage area and the at least one feeder beam having an associated feeder beam coverage area, the spot beam satellite having an antenna system configured to create a beam pattern having a plurality of different colors, wherein a color has a unique combination of frequency band and polarization, wherein the feeder beam coverage area is proximate to one or more of the service beam coverage areas, wherein the at least one feeder beam and a service beam associated with each of the one or more service beam coverage areas proximate to the feeder beam coverage area are allocated different colors from the beam pattern, such that signals associated with different colors differ by a frequency band, a polarization, or both a frequency band and a polarization, wherein the feeder beam coverage area is not proximate to one or more of the service beam coverage areas, and wherein a set of colors allocated to a service beam associated with each of the one or more service beam coverage areas not proximate to the feeder beam coverage area includes at least one same color allocated to the at least one feeder beam, such that signals associated with the same color have the same frequency band and polarization. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 28)
