摘要
σ星座作为一种具有独特星下点轨迹特性的特殊Walker星座类型,有关σ星座设计方法的描述在众多文献中相对缺乏,许多阐述也并不完备。基于此,深入研究了地面轨迹分离数与σ星座构型的关系,建立了σ星座空间几何模型,提出了一种σ星座设计解析方法。通过STK软件仿真验证了该设计方法的可行性,仿真结果表明,σ星座在高轨通信卫星星座和预警卫星星座的设计方面具有巨大的应用前景。
σconstellation is a special type of Walker constellation with unique sub-star track. There is relative less description on design method ofσconstellation in literatures.Even if there are some illustrations,they are incomplete.Therefore,the paper studies on the relationship between ground track separation values andσconstellation configuration in depth,builds up spatial geometrical model ofσconstellation and proposes aσconstellation design and analysis method.Through STK software imitation,the paper verifies the feasibility of the design method.The imitation result shows,there is a huge perspective forσconstellation in the design of high-track communication satel-lite constellation and warning satellite constellation.
