摘要
分布式卫星编队构形受大气摄动的影响会产生沿航迹方向的相对漂移。通过合理的面质比调整,可以降低漂移,提高构形稳定性。基于包含周日效应的大气密度模型,研究了编队卫星轨道能量耗散的差异,进而指出大气摄动引起的构形漂移与构形初始相位、以及轨道面和太阳密度周日峰方向夹角之间存在的关系。给出解析形式和数值方式2种面质比调整方法,并对后一种方法进行了仿真。仿真结果显示,利用文中给出的面质比调整方法,能够大大提高构形的稳定性。
An along-track drift may occur in the formation configurations of distributed satellite systems perturbed by atmosphere. An appropriate adjustment of area-mass-ratio can reduce this drift and improve the stability of the formation. The difference of orbital energy consumption between formation flying satellites is studied using the model of atmosphere density including daily effect, and it is indicated that the drift is determined by the formation initial phase and the angle between orbital plane and the direction of solar-density-daily-peak. Analytical and numerical methods are presented respectively for the adjustment of area-massratio, and the latter is used in an example. The simulation indicates that the presented adjustment method of area-mass-ratio can enormously improve the stability of formation configuration.
