Nonlinear attitude stability of a spacecraft on a stationary orbit around an asteroid subjected to gravity gradient torque
Yue Wang, Shijie Xu
The classical problem of attitude stability in a central gravity field is generalized to that on a stationary orbit around a uniformly-rotating asteroid. This generalized problem i…
Body-fixed orbit-attitude hovering at equilibria near an asteroid using non-canonical Hamiltonian structure
Yue Wang, Shijie Xu
Orbit-attitude hovering of a spacecraft at the natural relative equilibria in the body-fixed frame of a uniformly rotating asteroid is discussed in the framework of the full spacec…
Stability of the relative equilibria of a rigid body in a J2 gravity field
Yue Wang, Haichao Gui, Shijie Xu
The motion of a point mass in the J2 problem is generalized to that of a rigid body in a J2 gravity field. Different with the original J2 problem, the gravitational orbit-rotation…
Fourth-order gravity gradient torque of spacecraft orbiting asteroids
Yue Wang, Hong Guan, Shijie Xu
The dynamical behavior of spacecraft around asteroids is a key element in design of such missions. An asteroid's irregular shape, non-spherical mass distribution and its rotational…
On the Construction of Low-Energy Cislunar and Trans-lunar Transfers Based on the Libration Points
Ming Xu, Yan Wei, Shijie Xu
There exist cislunar and trans-lunar libration points near the Moon, which are referred as the LL1 and LL2 points respectively and can generate the different types of low-energy tr…
Gravity gradient torque of spacecraft orbiting asteroids
Yue Wang, Shijie Xu
Purpose: This paper presents a full fourth-order model of the gravity gradient torque of spacecraft around asteroids by taking into consideration of the inertia integrals of the sp…
