本研究探讨了编队飞行应用中多体系统的自然动力学。在惯性坐标系中确定适合多航天器保持松散编队的自然区域。将航天器编队定位在这些区域会导致航天器与编队指向方向之间的相互距离变化较小。这些合适的区域沿着参考轨迹近似二次曲面，并研究了二次曲面的动力学演化与参考轨迹特征结构的关系。
This investigation explores the natural dynamics in a multi-body regime for formation flying applications. Natural regions that are suitable to maintain multiple spacecraft in a loose formation are determined in an inertial coordinate frame. Locating a formation of spacecraft in these zones leads to a smaller variation in the mutual distance between the spacecraft and the pointing direction of the formation. These suitable regions approximate quadric surfaces along a reference trajectory and the relationship between the dynamical evolution of the quadric surfaces and the eigenstructure of the reference trajectory is examined.
