An Atlas of Optimal Low-Thrust Rephasing Solutions in Circular Orbit
Di Wu, Fanghua Jiang, Hexi Baoyin
In this paper, the time- and propellant-optimal low-thrust rephasing problems in circular orbit are studied to depict their solution spaces in an atlas. The number of key parameter…
Analytical Shaping Method for Low-Thrust Rendezvous Trajectory Using Cubic Spline Functions
Di Wu, Tongxin Zhang, Yuan Zhong +2
Preliminary mission design requires an efficient and accurate approximation to the low-thrust rendezvous trajectories, which might be generally three-dimensional and involve multip…
Real-Time Optimal Control for Irregular Asteroid Landings Using Deep Neural Networks
Lin Cheng, Zhenbo Wang, Yu Song +1
Precise soft landings on asteroids are central to many deep space missions for surface exploration and resource exploitation. To improve the autonomy and intelligence of landing co…
Systematic Low-Thrust Trajectory Optimization for a Multi-Rendezvous Mission using Adjoint Scaling
Fanghua Jiang, Gao Tang
A deep-space exploration mission with low-thrust propulsion to rendezvous with multiple asteroids is investigated. Indirect methods, based on the optimal control theory, are implem…
The First Data Release (DR1) of the LAMOST general survey
A. -L. Luo, Y. -H. Zhao, G. Zhao +140
The Large sky Area Multi-Object Spectroscopic Telescope (LAMOST) General Survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and…
Asteroid body-fixed hovering using nonideal solar sails
Xiang-yuan Zeng, Fang-hua Jiang, Jun-feng Li
Asteroid body-fixed hovering problem using nonideal solar sail models in a compact form with controllable sail area is investigated in this paper. The nonlinear dynamic equations f…
