A fuzzy-logic-based six-degrees-of-freedom (6DOF), that is, translational and rotational, controller for spacecraft operations was developed at the NASA Lyndon B. Johnson Space Center. The project objectives were to develop basic automated technologies and methodologies for intelligent systems for future space flight, particularly unmanned missions. Initial testing in simulation showed very good results for trajectory and attitude control. The final system was a 6DOF controller for proximity operations such as approach to target, station-keeping, and fly-around.
