1. A satellite for illuminating a geographic area with signals, the satellite comprising:

  • a transmission subsystem operable to generate a plurality of service link signals;

    a spot beam antenna system coupled to the transmission subsystem and operable to emit to create a plurality of service link spot beam signals each in a corresponding spot beam, wherein;

    each of the plurality of spot beams is operable to illuminate a distinct geographic area when the satellite is placed into orbit, andportions of a first one of the plurality of spot beams overlaps a second one of the plurality of spot beams so that a signal-to-interference ratio of a first one of said service link signals in the first one of said plurality of spot beams is interference-dominated by interference caused by a second one of the service link signals in the second one of the plurality of spot beams.
