圆轨道航天器八面体编队构型轨道动力学分析

提出一个全新的八面体航天器编队构型,该构型体现出当前编队飞行多种轨道构型的特征,同时也适于作为空间演示试验的编队飞行模式。八面体编队构型的设计思路是基于C-W方程,轨道平面内沿航向编队构型可利用轨道动力学自然保持,正上方或正下方编队构型则需要依靠平面内控制来实现,垂直轨道平面的编队构型需要施加法向控制来实现。对基于C-W方程的悬停动力学模型进行了精度分析,最后以低轨道航天器的八面体编队构型为例进行了数学仿真验证。

Analysis of Orbit Dynamics for Spacecraft Octahedron Formation Configuration in the Circular Orbit

A novel octahedron configuration of satellite formation flying was proposed.The characters of many formation flying configurations in recent years can be represented in this octahedron configuration.It is also suitble to the formation flying mode of the space demonstration project.The design method of octahedron formation configuration was based on the CW equation, and the along-track formation configuration in the orbit plane can be maintained using orbit dynamics.The above or below hanging formation configuration can be achieved using contorl in the orbit plane,and the formation configuration perpendicular to the orbit plane can be achieved using cross-track control.The precision of hanging dynamic model based on CW equation was analyzed in detail,and a low earth orbit satellite octahedron configuration was simulated for validation.
