保证用户公平性的低成本卫星星座设计
User-fairness guaranteed low-cost satellite constellation design
摘要
Abstract
In view of the challenges posed by the difference of user distribution and geographical environment to ensure user fairness under the service of satellite constellation,a LEO satellite constellation design scheme is proposed to guarantee the user fairness by comprehensively considering user demand,the level of communication development,and the level of disas-ter risk in different areas.The LEO Satellite Network model is established and the coverage performance of a single satellite is analyzed.The user fairness factor is defined,and the optimization problems for LEO satellite constellation are formulated by minimizing the constellation investment cost and maximizing the coverage rate while satisfying user fairness.The LEO satellite constellation design problem under the constraints of constellation capacity and constellation profit is solved using a Non-dominated Sorting Genetic Algorithm(NSGA-Ⅱ).Simulation results demonstrate that the designed satellite constella-tion can meet the requirements of user fairness in different areas with low satellite constellation investment cost,and simul-taneously satisfy the coverage rate for the target area.关键词
