摘要
介绍了卫星星座的设计原则,给出了星座参考卫星6个开普勒轨道根数与星座参数的设计方法,针对有效监视全球热点区域提出了一种卫星星座设计方案,并进行了仿真分析。采用太阳同步轨道,以日为回归周期,2 h重访,每次可对热点区域提供30 min或者20 min连续观测时间。
This paper describes the design principles for a satellite constellation. It then presents the six Keplerian elements of the reference satellite of the constellation and the design method for the constellation parameters. Furthermore,this paper proposes a design of miniaturized satellite constellation, which can provide efficacious surveillance of hot spots across the globe. An analysis of the constellation is made by means of simulation. Satellites making up the constellation move in sun-synchronous orbits and have a one-day recurrence cycle. This allows the constellation to re- visit an area every 2 hours to provide continuous observation of a hot spot for about 20 or 30 minutes each time.
