Abstract
A vehicle is described herein that is capable of operating in space. The vehicle comprises a memory that stores computer-executable instructions. The vehicle further comprises a processor in communication with the memory, wherein the computer-executable instructions, when executed by the processor, cause the processor to: derive an equation of motion for the vehicle; determine an initial guess of a first value of a costate of the vehicle; determine the first value of the costate for a minimum time transfer in averaged orbit dynamics using the equation of motion, the initial guess, and a single shooting technique; determine a second value of the costate for the minimum time transfer in full-state orbit dynamics using the first value of the costate and the single shooting technique; and adjust a path of the vehicle to cause the vehicle to travel along an optimal transfer in full-state orbit dynamics.
