Abstract: A control system includes a target spacecraft and a swarm of chaser spacecraft. Each chaser spacecraft is controlled to follow a corresponding computed trajectory. The system also includes at least one computing device that executes a nested genetic algorithm. The nested genetic algorithm includes multiple guidance genetic algorithms and an outer genetic algorithm. Characteristically, each chaser spacecraft has an associated guidance genetic algorithm that determines a computed trajectory for the chaser spacecraft associated therewith. Advantageously, the outer genetic algorithm checks for collisions and is configured to alter one or more computed trajectories to avoid collisions.
