This work is aimed to introduce a strategy that may help reach the conclusion that using lasers in space is one of the most promising methods to reduce the risk of collisions between active satellites and middle-size LEO debris.

The strategy accounts for the implementation of the post-Newtonian (p-N) corrections that are decisive to reach the accuracy required by some Just-in-Time Collision Avoidance (JCA) space-based methods.

In fact, we show how and why all JCA methods similar to the one introduced here, which involves simple formations of trackers in Sun-synchronous orbits (SSO), would be within the most efficient to throw middle size debris objects into the Atmosphere by laser ablation, as long as the trackers can implement these corrections while the objects are targeted.

对 JCA 的后牛顿修正

这项工作旨在介绍一种策略,该策略可能有助于得出结论,即在太空中使用激光是降低活动卫星与中型 LEO 碎片之间碰撞风险的最有希望的方法之一。

该策略考虑了后牛顿 (pN) 校正的实施,这些校正对于达到某些即时防撞 (JCA) 空间方法所需的精度具有决定性意义。

事实上,我们展示了与此处介绍的类似的所有 JCA 方法(包括在太阳同步轨道 (SSO) 中简单地形成跟踪器)如何以及为什么能够以最有效的方式通过激光将中等大小的碎片物体抛入大气层消融,只要跟踪器可以在目标对象被定位时执行这些校正。
