Space-based communication system and method with continuous channel reuse maintenance

A system comprising:

• a plurality of satellites;
• and
• a base station that is capable of communicating with the satellites and includes means for performing a reuse maintenance method that computes interference potentials between a reference reuse unit being used by a first satellite and reuse units being used by the other satellites, for determining each of the interference potentials based on a physical distance between a center of a first beam that uses the reference reuse unit and each of a center of second beams that uses one of the reuse units and a correlation factor and for assigning a non-interfering reuse unit to the first satellite when each of the interference potentials are less than a threshold interference potential.

A method of reuse channel management comprising the steps of:

• (a) computing interference potentials between a reference reuse unit being used by a first satellite and reuse units being used by second satellites by determining each of the interference potentials based on a linear distance between a center of a first beam that uses the reference reuse unit and each of a center of second beams that use the reuse units and a correlation factor;
• and
• (b) assigning a non-interfering reuse unit to the first satellite when each of the interference potentials are less than a threshold interference potential.
