First Claim
1. A system comprising:
- one or more non-transitory computer-readable mediums having instructions stored thereon that, when executed by one or more processors, cause the system to;
determine a current location of a mobile satellite terminal comprising an antenna configured to send and receive RF signals;
identify a plurality of user spot beams providing coverage to the determined current location;
calculate a normalized distance metric for each of the plurality of user spot beams;
identify a user spot beam of the plurality of user spot beams having a lowest normalized distance metric; and
select the user spot beam having the lowest normalized distance metric and a satellite associated with the user spot beam having the lowest normalized distance metric.

Abstract
An apparatus for satellite selection within a multi-satellite communication system, comprising an antenna, receiver, and transmitter, and a processing module configured to calculate a normalized distance metric for the plurality of user spot beams of a first and second satellite, select the user spot beam with the lowest normalized distance metric, and determine which of the at least first or second satellite is transmitting the selected user spot beam. Further, a method for increasing the aggregate capacity of a satellite communications network, comprising identifying high traffic regions within a coverage area of a first satellite, determining which user spot beams of the first satellite are available to each of the identified regions, determining a normalized distance metric for each user spot beam identified, and plotting a second beam pattern of a second satellite to produce at least one user spot beam with a lower normalized distance metric.
