Relative Motion Modeling and Autonomous Navigation Accuracy

Abstract

This research developed a methodology for determining the required accuracy of the dynamic model based on system requirements, the relative navigation accuracy and thruster accuracy. A state transition matrix was developed to propagate satellite relative motion to include non-conservative forces and the effect of higher order gravitational terms. The models developed were validated using numerical simulations.
