Assume that a constellation of satellites is required to remain close to a given nominal trajectory and that there is some freedom in the selection of the geometry of the constellation. If we are interested in avoiding large variations of the mutual distances between the spacecraft, we can consider the possible existence of regions of zero relative radial acceleration with respect to the nominal trajectory. The motion along these regions will reduce the expansion or contraction of the constellation. The goal of this paper is the study of these regions and the controlled motions between them.

零相对径向加速度圆锥和受控运动，适合编队飞行

假设需要一个卫星群保持接近给定的标称轨迹，并且在选择该星座的几何形状时有一定的自由度。如果我们有兴趣避免航天器之间的相互距离发生较大变化，则可以考虑相对于标称轨迹的相对径向加速度为零的区域的可能存在。沿着这些区域的运动将减少星座的膨胀或收缩。本文的目的是研究这些区域及其之间的受控运动。
