Communication system as a secondary platform with frequency reuse
View Patent ↗A communications system ( 10 ) and method of operating the communications system includes a first stratospheric platform generating a second beam having a frequency the same as a satellite beam to the same service area. User terminals are configured to receive the first beam or the second beam.
1. A communication system for use with geosynchronous satellite systems broadcasting a first beam at a first frequency comprising:
a first stratospheric platform generating a second beam having the first frequency;
a second stratospheric platform generating a third beam having the first frequency; and
user terminals configured to receive the first beam, the second beam and the third beam.
2. A system as recited in claim 1 wherein user terminals comprise directional antennas.
3. A system as recited in claim 1 wherein the second beam is generated from a secondary payload.
4. A communication system for use with geosynchronous satellite systems broadcasting a first beam at a first frequency comprising:
a first stratospheric platform having a primary payload and a secondary payload, said secondary payload generating communication signals having the first frequency.
5. A system as recited in claim 4 further comprising a second stratospheric platform generating a third beam having the first frequency.
6. A method for operating a communications system comprising the steps of:
generating a first beam using a first frequency directed at a service area with a satellite;
generating a second beam using the first frequency directed at the service area from a first stratospheric platform; and
generating a third beam using the first frequency directed at the service area from a second stratospheric platform.
7. A method as recited in claim 6 wherein said step of generating a second beam comprises the step of generating a second beam from a secondary payload.
8. A method as recited in claim 6 wherein said satellite comprises a geostationary satellite.
9. A method as recited in claim 6 further comprising the step of generating a feeder link with the first frequency.
10. A system as recited in claim 1 further comprising a gateway station generating a feeder link using the first frequency.
11. A communication system for use with geosynchronous satellite systems broadcasting a first beam at a first frequency range comprising:
a first stratospheric platform generating a second beam, a plurality of third beams and a plurality of fourth beams each within the first frequency range within a service area, said plurality of third beams and said plurality of fourth beams alternately arranged around the second beam in a center position to provide a three color rouse scheme;
user terminals configured to receive beams in the first frequency range.
12. A system as recited in claim 11 wherein user terminals comprise directional antennas.
13. A system as recited in claim 11 wherein the second beam is generated from a secondary payload.
14. A communication system for use with geosynchronous satellite systems broadcasting a first beam at a first frequency range comprising:
a first stratospheric platform generating a plurality second beams and a plurality of third beams each within the first frequency range and a service area, said plurality of second beams and said plurality of third beams alternately arranged around a central hole;
a gateway station positioned within the hole in the service area;
user terminals configured to receive beams in the first frequency range.
15. A system as recited in claim 14 wherein user terminals comprise directional antennas.
16. A system as recited in claim 14 wherein the plurality of second beams are generated from a secondary payload.
