In this work, we introduce a modified double-averaging approach by considering the short-
term effects and formulate a more accurate double-averaged Hamiltonian (in comparison to …

The halo orbits of the spatial circular restricted three-body problem are largely considered in
space-flight dynamics to design low-energy transfers between celestial bodies. A very …

In this work, a semi-analytical model is formulated up to an arbitrary order in the semimajor
axis ratio of the inner and outer binaries to describe the long-term (secular) dynamics of test …

The multi-revolution elliptic halo (ME-Halo) orbit is a kind of strictly periodic orbit existing in
the elliptic restricted three-body problem (ERTBP) model. Its remarkable features include …

In this paper, a three-maneuver strategy is presented to study the transfer from a cislunar L 2
halo orbit to a low lunar orbit (LLO). Both the cislunar L 2 point orbits and lunar orbits are …

High-order series expansions around triangular libration points in the elliptic restricted three-
body problem (ERTBP) are constructed first, and then with the aid of the series solutions, two …

In view of the shortcomings of existing satellite navigation systems in deep-space
performance, candidate architectures which utilise libration point orbits in the Earth-Moon …

Based on the candidate architectures of the libration point satellite navigation system
proposed in our previous work, a navigation performance study is conducted in this paper to …

Single-impulse and low-thrust low-energy transfers from a Lyapunov orbit around L_2 L 2
point of the Sun–Earth system to the periodic orbits around the equilibrium points L_i\;(i= 3 …

Several families of periodic orbits exist in the context of the circular restricted three-body
problem. This work studies orbital motion of a spacecraft among these periodic orbits in the …
