大型低轨星座构型演化分析及维持控制策略研究
Evolution Analysis and Maintenance Control Strategy Study on LEO Mega-Constellation Configuration
摘要
Abstract
In view of the configuration maintenance control problem of low-Earth-orbit(LEO)mega-constellations,a process for the evolution analysis and maintenance control of constellation configuration is established.The process is suitable for the constellation configuration evolution analysis and maintenance control of LEO Walker satellites of 1 000 magnitude.The relative configuration preservation method without mean drift deviation is used to analyze the constellation configuration evolution,which not only effectively minimizes the control frequency,but also balances the control satellite distribution.Besides,a free segment maintenance strategy is adopted to orderly plan the control timing and position of each satellite,which realizes an orderly and decentralized control in time and space dimensions.The presented process and method reduce the negative impact on constellation service performance,and offer a significant advancement in the field of mega-constellation configuration maintenance control.关键词
