1. A method for increasing the bandwidth of a satellite system, the satellite system comprising a plurality of satellites, wherein the plurality of satellites are arranged in multiple planes, with a nominal number of satellites in each plane, wherein the method comprises:
- establishing, between a minimal-set satellite network portal (SNP) having a first coverage area and a first one of at least two gateway antennas disposed on at least one satellite of the plurality thereof, a first communications link having a first bandwidth; and
establishing, between an interstitial SNP having a second coverage area and a second one of the at least two gateway antennas disposed on the one satellite of the plurality thereof, a second communications link having a second bandwidth, wherein the second coverage area overlaps at least a portion of the first coverage area;
channelizing, into a first group of channels each of which channels is associated with a different range of frequencies than the other channels in the first group, a first gateway beam received by the one satellite over the first communications link;
channelizing, into a second group of channels each of which channels is associated with a different range of frequencies than the other channels in the first group, a second gateway beam received by the one satellite over the second communications link, wherein;
(a) the first and second groups have the same number of channels,(b) for each channel having a particular range of frequencies in the first group, there is a channel in the second group having the same range of freauencies; and
summing channels from the first group and the second group that have the same range of frequencies.

7. A method for increasing the bandwidth of a satellite system, the satellite system comprising a plurality of satellites, wherein the plurality of satellites are arranged in multiple planes, with a nominal number of satellites in each plane, wherein the method comprises:
-
disposing an interstitial satellite network portal (SNP) having a first coverage area relatively closer to a first minimal-set SNP than the first minimal-set SNP is to any other minimal-set SNP; and establishing a communications link between the interstitial SNP and one of at least two gateway antennas disposed on one satellite of the plurality thereof, wherein the communication link transmits an interstitial gateway beam that increases bandwidth nominally provided to the satellite by a communications link established between the first minimal-set SNP and a second of the at least two gateway antennas disposed on the one satellite of the plurality thereof; forming a first group of channels from a gateway beam received over the communications link between the minimal-set SNP and the second gateway antenna; increasing the nominal number of satellites per plane; deactivating a first radio transceiver of a plurality thereof on the one satellite; and re-allocatina, to a second radio transceiver of the plurality, a first channel of the first group of channels that was formerly allocated to the first radio transceiver, wherein the second radio transceiver transmits a beam to a first geographic region. - View Dependent Claims (8, 9, 10, 11)

12. A method for increasing the bandwidth of a satellite system, the satellite system comprising a plurality of satellites, wherein the plurality of satellites are arranged in multiple planes, with a nominal number of satellites in each plane, wherein the method comprises:
-
disposing an interstitial satellite network portal (SNP) having a first coverage area relatively closer to a first minimal-set SNP than the first minimal-set SNP is to any other minimal-set SNP; and establishing a communications link between the interstitial SNP and one of at least two gateway antennas disposed on one satellite of the plurality thereof, wherein the communication link transmits an interstitial gateway beam that increases bandwidth nominally provided to the satellite by a communications link established between the first minimal-set SNP and a second of the at least two gateway antennas disposed on the one satellite of the plurality thereof; forming a first group of channels from a gateway beam received over the communications link between the minimal-set SNP and the second gateway antenna; forming a second group of channels from the interstitial gateway beam; and
summing channels from the first group and the second group;increasing the nominal number of satellites per plane; deactivating a first radio transceiver of a plurality thereof on the one satellite; and re-allocating, to a second radio transceiver of the plurality, a first channel of the first group of channels and a first channel of the second group of channels, both of which channels being formerly allocated to the first radio transceiver, wherein the second radio transceiver transmits a beam to a first geographic region. - View Dependent Claims (13)
