This paper presents a framework for automated impulsive transfer design with a view toward onboard application. A database of periodic orbits and other structurally important trajectories is combined with large-scale simulations to create a discrete representation of the system dynamics. A heuristic search is used to quickly find paths in this discretization, which generate a set of arcs and impulses approximating a continuous transfer between boundary conditions specified in the original system. Differential correction and partial optimization are used to create a final, feasible transfer. Each step will be described, with a focus on the construction of a weighted, directed graph representation of the transfer problem, as well as the search process and its relation to the final transfer.
