| 摘 要： | 研究了在高空电离层中运动的带电荷的卫星受电感应阻力后对轨道根数产生的摄动影响。研究结果表明 ,电感应阻力对带电卫星的轨道半长轴、轨道偏心率、近地点赤经、历元平赤经均有周期摄动影响 ,但除对半长轴有长期摄动效应外对其它轨道根数均无长期摄动。轨道倾角和升交点赤经不受摄动影响。文中以飞行在高度 1 50 0km的电离层中的导体卫星作为算例。计算结果显示 :带电导体卫星在高空电离层中带有一定电量时电感应阻力对轨道半长轴的缩短产生显著效应

| Abstract: | The influences of the electronic induction drag on the variation of the orbital elements of a charged satellite moving in a magnetic-field-free ionosphere are studied.The theoretical result show that the induction drag results in both the secular and periodic variation of the semi-major axis,however the eccentricity,the argument of perigee and the mean longitude of epoch exhibits no secular variation,but only periodic variation.The inclination and the ascending node remain no variation.As example,the secular effect of the induction drag on the orbital semi-major axis at a supposed satellite is calculated.It can be shown that the semi-major axis is contracted due to the induction drag,if this satellite carries many charges in an ionosphere. |
