The granted patent (Publication Number: US11923961B2) discloses a method and system for generating an optimized beam layout for a satellite in a satellite communications system. The method involves receiving terminal and/or network data, identifying high-traffic terminals, determining overlay beams, optimizing beam center positions, and deriving an optimized beam layout. The system includes an input for receiving data and a processor for executing the steps of identifying high-traffic terminals, optimizing beam center positions, and deriving the optimized beam layout.

Furthermore, the method and system allow for iterative optimization of beam layouts based on changing terminal and/or network data over time. The processor iteratively optimizes beam center positions and derives an optimized beam layout while inhibiting changes below a threshold criterion. This approach ensures efficient and effective satellite communication by adapting to evolving communication terminal distributions and network conditions. The system's ability to merge adjacent beams, synthesize beam weights, and quantize the optimized beam layout enhances the overall performance and coverage of the satellite communications system, making it a valuable innovation in the field of satellite technology.
