“…Candidate trajectories were used as initial guesses for GALLOP. Later, Morante et al [22] combine this shape-shaped method with a GA to automatically obtain the number and sequence of flybys for various interplanetary missions in the tool MOLTO-IT. He proved that the shaped based method was suitable for providing initial guesses for more accurate optimization algorithms.…”

In this paper, we provide a survey on available numerical approaches for solving low-thrust trajectory optimization problems. First, a general mathematical framework based on hybrid optimal control will be presented. This formulation and their elements, namely objective function, continuous and discrete state and controls, and discrete and continuous dynamics, will serve as a basis for discussion throughout the whole manuscript. Thereafter, solution approaches for classical continuous optimal control problems will be briefly introduced and their application to low-thrust trajectory optimization will be discussed. A special emphasis will be placed on the extension of the classical techniques to solve hybrid optimal control problems. Finally, an extensive review of traditional and state-of-the art methodologies and tools will be presented. They will be categorized regarding their solution approach, the objective function, the state variables, the dynamical model, and their application to planetocentric or interplanetary transfers.

“…The transcription method is based on the Hermite-Simpson collocation approach and the interior-point solver IPOPT is employed as NLP solver. The interested reader is encouraged to check [26] and [27] where a similar approach is used to optimize low-thrust interplanetary transfer. For computing impulsive manoeuvres, the algorithms presented in [26] and [27] can be applied by optimizing the location, magnitude and direction of the chemical manoeuvres, instead of the timediscretized history of the low-thrust steering angles.…”
