soft lunar landing

基本解释

It is one of the most important technologies for guidance and control of lunar soft landing at main braking phase.
本文针对月球软着陆的最终着陆段，提出了一种利用绳索进行软着陆的新方案。
The descending trajectory and the guidance method were presented for the braking phase of lunar soft-landing from a circular orbit.
对自环月轨道开始的月球软着陆制动段飞行轨迹和制导律进行了研究。
Firstly, based on simplified dynamics of lunar soft landing, an explicit guidance law was induced by solving the special two-point boundary value problem.
首先，基于简化的软着陆动力学模型，通过求解特殊两点边值问题，给出了一种实时显式制导方法。
