Abstract
Summary: Multi-satellite coordinated missions can improve upon larger solitary satellite missions through greater flexibility, efficiency, scalability and redundancy. This study considers a more diverse approach to in-orbit motion coordination that reduce dependence on communication links and absolute position references. The non-linear relative equations of motion applied to a chief satellite and a deputy target in the LEO orbit are considered and a feedback control system to facilitate multi-satellite relative motion coordination is designed. The feedback controller relies on on-board optical sensor measuring optic flow signal, similar to the bio-inspired feedback-controlled systems used for various aerial operations. Performance in orbit is analyzed by means of multiple numerical simulations on a rendezvous scenario with a target in LEO orbit. A ground-based experimental testbed is designed for validation of the feedback control framework for space- borne optical systems.
