The rise in launch and use of small satellites in the past decade, a result of improved
functionality through technology miniaturisation and alternative design philosophies, has …

The autonomous formation flying of multiple spacecraft to replace a single large satellite will
be an enabling technology for many future missions. In this research, the current status of …

A new constellation configuration is proposed to provide near‐constant communications
between any two points in the cislunar space. Four satellites were allocated on some natural …

地月L2 点附近轨道具备独特的动力学和运动学特性, 是月球背面探测任务的中继卫星首选布设
位置. 面向未来月球背面探测任务的中继通信需求, 分析并研究了地月L2 点周期轨道(halo 轨道) …

In this article, a method for satellite constellation build-up is presented based on three-body
dynamics. This method enables satellite constellation build-up with single launch and less …

As the demand for services from Space is more and more important to life on the Earth, the
international interest in satellite constellations is increasingly growing. For example, in the …

Halo orbit nearby the Earth-Moon libration points is valuable to explore the lunar farside,
which however must frequently be controlled to stay in the vicinity of libration points because …

This paper addresses contingency trajectories of CHANG'E-3 in the case of a failure of the
lunar brake, which is crucial to the CHANG'E-3 mission, ie, the first Chinese lunar soft …

Since the halo orbits in the vicinity of the collinear libration points have a strong hyperbolic
character, it is possible to use their stable manifold for the transfer from the Earth. However …

Abstract Orbits nearby the Earth-Moon libration points have the specific dynamic
characteristicsand are the preferred position of relay satellites for the lunar farside …
