Abstract

All-electric spacecraft makes numerous revolutions during the orbit-raising to the geosynchronous equatorial orbit. This paper presents a new mathematical formulation to describe the dynamics of the spacecraft under the action of continuous thrust. Furthermore, it presents a new optimization framework that considers the proposed dynamic model to solve a sequence of optimization sub-problems for rapid and robust generation of the low-thrust orbit-raising trajectories. It is considered that the spacecraft does not thrust in the shadow of the Earth. Numerical results for different orbit-raising mission scenarios are presented to illustrate the performance of the algorithm.
