The Global Resource Manager (GRM) acts as a central coordination tool for the next generation of beamforming satellite systems providing mobile service. This system planning tool establishes resource plans which coordinate between satellite and terrestrial networks to allow sharing spectrum and to determine operational rules for the satellite base stations. The GRM provides numerous functions for both developing and analyzing new and existing plans, including support for beamforming, performing capacity analyses (based on traffic profiles), and link budgets. The system is capable of generating plans with both uniform and non-uniform frequency-reuse patterns and beam sizes. Requirements may be assigned to beams individually or may be assigned to a group of beams within a specified region. Numerous other constraints can be built directly into the GRM, such as frequency and power sharing with ancillary terrestrial component (ATC) stations as well as specific Federal Communication Commission (FCC) and satellite limits. As such, the GRM provides a complete solution for generating resource plans for Mobile Satellite Service (MSS).
