查询词典 elliptical

Because of the secular perturbation variations of the ascending node right ascension, the argument of perigee and the mean angle caused by the initial deviations of the semi-major axis, the inclination and the eccentricity are linear time-variant, then the active biases of the semi-major axis, the inclination and the eccentricity can realized the self-stabilization design of the elliptical orbit satellite constellation, and so the configuration stability will be improved.

通过初始偏差对椭圆轨道卫星的长期影响分析可知，轨道半长轴、倾角和偏心率的初始偏差对升交点赤经、近地点幅角和平近点角的长期摄动变化是线性的，因此通过主动偏置轨道半长轴、偏心率和倾角能够实现椭圆轨道星座构型的自稳定设计，从而提高其构型稳定性。
