Intra-vehicular free-flyer high accuracy navigation using Pseudolites

A new intra-vehicular free-flyer location and navigation methodology is introduced which adopted the state of art radio location and navigation technology called Pseudolite (PL). Theoretical analysis demonstrates the efficiency of this method. It will greatly improve intra-vehicular free-flyer navigation accuracy to satisfy future needs in deep space exploration and space structure maintenance. PL system measurement model and navigation algorithm are given along with recommendations for future research.
