A novel approach based on virtual gravitational body (VGB) is proposed for low-thrust trajectory optimization in this paper. To represent the low-thrust trajectory in an analytical form, a VGB, whose gravity on the spacecraft is equivalent to the resultant of the Sun gravity and the low-thrust, is introduced. Firstly, it is assumed that the VGB stays stationary in each trajectory segment to recover...
For low-thrust trajectories optimization, an improved direct-shooting method is proposed to overcome the two major drawbacks of the original one: the low-thrust trajectories are computed inefficiently using explicit numerical integration; and the control steering profile is more likely to converge at local optimum due to its local linear interpolation characteristics. The measures taken in this work...
