The Global Resource Manager (GRM) optimizes spectrum, beam, power levels, coverage and other resources for next generation mobile satellite systems. The GRM establishes resource plans which coordinate between satellite and terrestrial networks to allow for spectrum sharing and the determination of operational rules for satellite base stations. Additionally, the GRM optimizes beam coefficients to achieve desired regional and spot beam shapes. 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), International Telecommunication Union (ITU) and satellite limits. As such, the GRM provides a complete solution for generating resource plans for Mobile Satellite Service (MSS).
The GRM was developed for the Terrestar satellite and terrestrial 4G mobile telecommunication network program and operates in their Network Control Center (NCC). The TerreStar satellite has a ground based active beamformer that generate over five hundred beams across North America. The GRM optimizes power, frequency and coverage plans as well as beam shapes that intelligently suppress sidelobes in order to maximize capacity while meeting interference constraints to legacy ground based fixed service stations.
