面向非地面网络多QoS保障的低地球轨道卫星星座设计
LEO satellite constellation design with multi-QoS guarantee for non-terrestrial network
摘要
Abstract
LEO satellite constellation(LSC)offers seamless and fast connectivity for non-terrestrial network(NTN).However,the lack of QoS guarantees for users significantly impacts the performance of the NTN system.Considering multi-QoS metrics,a capacity and downlink budget model for LSC was established,and subsequently,the establishment of inter-satellite links was framed as a link budget issue for the QoS guarantee.The non-dominated sorting genetic algo-rithm(INSGA-II)with improved crossover and mutation operators was proposed to optimize LSC,aiming to maximize coverage and system capacity while minimizing constellation costs.The numerical results demonstrate that the designed LSC exhibits comparable or superior performance to Telesat and Kepler,and its scale is only 64%of the Kepler system.关键词
