A Novel Spot Beam Deployment Procedure for High-Capacity Satellites Technology #017-016-ai-liping Categories Communication Researchers Liping Ai Patent Protection Provisional Patent Application Filed Description Researchers at George Washington University have developed a novel satellite spot beam deployment procedure which can be used in simulations for channel and system performance assessment in the early stage of high capacity satellite (HCS) system ground segment design. The HCS system designers and operators can use this procedure to improve ground segment design. The HCS systems are revolutionizing the communications services offered by the communications satellites.The HCS systems are complex. The design of such a system calls for simulations and optimization accounting for the geographic service area, spectrum of operation, satellite position in orbit, user population, traffic mix, and performance requirements. Savings in computation time and data storage space of such simulation are very much desirable. Researchers at George Washington University have developed a novel satellite spot beam deployment procedure which can be used in simulations for channel and system performance assessment in the early stage of a HCS system ground segment design. The procedure approximates the spot beam power spatial distribution with high accuracy by a Ka-band satellite antenna radiation pattern and requires considerably less computation compared to other methods. It is applicable to any satellite antenna radiation patterns as a function of the elevation angle and independent of the azimuth angle. The majority of the Ku-band and Ka-band satellite antenna patterns meet this requirement. The simplicity and good accuracy make it an attractive component product in the complex simulation software for the HCS system design. The HCS system designers and operators would use this procedure to perform better ground segment design. With the over-the-air-reconfiguration capability today, the redesign of the ground segment during operation to meet the changing service requirement would be possible with time saving design tools of software in smaller scale. In addition to the HCS system designers and operators, any other satellite system designers and operators using satellites at high altitudes and spot beam footprints for their service coverage areas can use this procedure in simulation or use it alone with an amended user interface for ground segment design via earth stations’ performance assessment and prediction.
