Communications system using a satellite-based network with a plurality of spot beams providing ubiquitous coverage from two different satellites
First Claim
1. A satellite system operating over a land mass comprising:
- a first satellite generating a first plurality of spot beams directed at said land mass, said first set of spot beams partially covering said land mass;
a second satellite generating a second plurality of spot beams;
said first plurality of spot beams and said second plurality of spot beams in combination provide substantially ubiquitous coverage over the land mass Wherein at least one of said first plurality of spot beams having a plurality of beam segment portions, said plurality of beam segment portions being independently adjustable in response to a condition, wherein said condition is heavy traffic routed through said satellite.

Abstract
A satellite-based communications system operating at high data rates includes a plurality of satellites each having uplink and downlink antennas for transmitting and receiving a plurality of signals utilizing a plurality of spot beams to and from a plurality of coverage areas at a predetermined range of frequencies. The system can include, or be combined with, other systems to enable increased capacity over high population areas and ubiquitous coverage over lower population areas. A portable antenna assembly can be coupled to a user'"'"'s portable or mobile electronic device for coupling the electronic device directly to a satellite. A routing switch provides routing and switching on-board the satellite and routes signals according to their desired destination.
