Initialization and resizing of formation flying using global and local optimization methods

This work presents a method to initialize and resize spacecraft formations using a combination of global and local optimization techniques. The method presented uses a two-step process. First, using genetic algorithms, we search for the best subset of target states such that the total formation initialization delta-V using a two-burn Lambert solution is minimized based on mission specific constraints. Second, we use Lawden´s primer vector theory to find the optimal number and location of maneuvers to achieve the desired formation.
