HIGH CAPACITY SATELLITE COMMUNICATIONS SYSTEM
First Claim
Patent Images
1. A high capacity satellite communications system comprising:
- at least one satellite with at least one beam for a forward downlink focused on a first geographic coverage area;
at least one hub located in a second geographic coverage area which is different from the first geographic coverage area, the first geographic coverage area and the second geographic coverage area configured with disproportionate amounts of bandwidth capacity such that the first geographic coverage area provides more bandwidth capacity and the second geographic coverage area provides less bandwidth capacity; and
at least one VSAT located in the first geographic coverage area where a first beam for the forward downlink received by the VSAT from a satellite does not overlap with a second beam for a return downlink received by a hub from the satellite.

Abstract
A high capacity satellite communications system including a satellite with a beam for a forward downlink focused on a geographic area for which disproportionately higher capacity is desired, a hub located in a geographic area for which disproportionately lower capacity is desired, compared to the location of a VSAT, and the VSAT located in area where a beam for a forward downlink received by the VSAT from the satellite does not overlap with a beam for a return downlink received by the hub from a satellite.

18. A method for a high capacity satellite communications system comprising:
-
constructing at least one hub, wherein at least one VSAT is located in a first geographic coverage area, and the at least one hub is located in a second geographic coverage area which is different from the first geographic coverage area, the first geographic coverage area and the second geographic coverage area configured with disproportionate amounts of bandwidth capacity such that the first geographic coverage area provides more bandwidth capacity and the second geographic coverage area provides less bandwidth capacity; configuring the at least one hub to use a return bandwidth that is no more than half a forward bandwidth; and configuring at least one satellite to use as few carriers as possible based on the continuity of the frequencies available to the at least one satellite. - View Dependent Claims (19, 20, 21, 22)
