Abstract
This paper introduces a segmented approach for solving constrained orbit transfer problems. The segments are connected through continuity constraints under the Theory of Functional Connections (TFC) mathematical framework that performs linear functional interpolation. This approach is further enhanced by a general vector formulation, from where the constrained functional is derived considering also a set of linear overdetermined constraints. Since we constrain vector instead of coordinates, this methodology allows to apply TFC to multiple and complex constraints composed by any types of nonlinear components included. We demonstrate the effectiveness of the method on Earth-to-Moon transfers, showing that this segmented approach achieves solutions with several orders of magnitude greater accuracy and efficiency in comparison with unsegmented orbit transfers.
