An Application of the A* Search to Trajectory Optimization
Abstract
As space operations become more complex and ambitious, there is a corresponding increase in the sophistication required of on-board algorithms for proximity operations. Unmanned missions such as planetary probes require sophisticated algorithms to deal with evolving mission requirements and contingencies, where man-in-the-loop control will be impractical. Other future missions that require autonomy for safety or security reasons will also require intelligent on-board controllers. This effort discusses a structure for a candidate proximity operations controller and provides initial development of an intelligent trajectory planner in three degrees of freedom using the A * Node Search technique.
