摘要
通过施加冲量的方法消除J2项摄动和大气阻力摄动对编队飞行的影响,在编队的相对构型和整体绝对位置得到控制后,研究了低轨卫星编队飞行的地面覆盖问题,最后通过算例给出了卫星编队在南北纬86°之间全球覆盖所需的时间、周期、圈数和覆盖角。计算结果表明,对于偏心率较小的低轨编队飞行,根据本文所推导公式计算出的结果是比较可靠的。
This paper presents a method to eliminate the effect of J2 perturbation and atmospheric drag perturbation to the formation flying by putting an impulse on satellites. After having controlled the relevant configuration and the integral absolute location of the formation, the paper analyzes the problem of surface coverage of satellite formation flying in low earth orbit. Finally, the paper gives experiments calculating the time, the period, the amount of circles and the coverage angle needed for global coverage of the satellite formation flying between latitude 86 degrees in south and that in north, The results come out from the formulas deduced in this paper are quite reliable for the formation flying in low earth orbit with small eccentricity.
