基于Gibbs方法的编队飞行轨道设计

Formation Flying Orbit Design Based on Gibbs Method

编队飞行中各卫星的轨道根数具有微小差别,为了使编队的相对轨道比较理想,各卫星的轨道参数需要精确设计。编队飞行轨道设计通常基于近似化的相对运动方程,通常,基于单点法计算得到的环绕轨道不唯一,且不易得到一条确定的并与期望轨道准确吻合的环绕轨道,文中给出基于Gibbs法的多点设计方法,在计算中考虑了环绕轨道的多个特殊点,且在计算中避免引入相对速度速度,使轨道计算更精确,环绕轨道与期望轨道基本吻合。

Elements of orbit of satellites in formation are distinctness appreciably. For relative trajectory is more idealized . elements of each satellite need to be calculated accurately. The relative trajectory from the 'One-point' method can t tally with the expectation, because orbit design of formation is always based on approximate equations of relative motion. Another method named 'Several-point' is show in this paper,that is base on the Gibbs method, can avoid the appearance of grave error, and the relative trajectory from this method can tally with the expectation preferably.
