论文摘要
在2029年，卫星在其地球接近近距离接近小行星apophis方面的动力学和控制得到了评估和研究。首先，评估并显示出可行的近心轨道相时，在其中心轨道相中进行有关apophis的近距离操作的可行性。然后，分析了相对于Apophis的三种不同类型的近距性运动，这将使航天器能够在整个地球接近接近接近接近。这些维持一个远离apophis的相对轨道，沿着地球植物线徘徊，或通过飞by维持围绕apophis的轨道。这些都被证明是可行的，尽管具有挑战性，并且这些操作的一些基本方面被注意到并讨论。
The dynamics and control of a satellite in proximity to the asteroid Apophis across its Earth close approach in 2029 is evaluated and investigated. First, the feasibility of carrying out close proximity operations about Apophis when in its heliocentric orbit phase is evaluated and shown to be feasible. Then three different types of close proximity motion relative to Apophis are analyzed that will enable a spacecraft to take observations throughout the Earth close approach. These are maintaining a relative orbit that is somewhat distant from Apophis, hovering along the Earth-Apophis line, or maintaining orbit about Apophis through the flyby. Each of these are shown to be feasible, albeit challenging, and some basic aspects of these operations are noted and discussed.
