Research on relative position and attitude representation and algorithm of formation flying systems based on position and attitude dual quaternion model

Abstract

To combine the attitude into spacecraft’s orbit representation in formation flying systems, this article addresses a novel position and attitude dual quaternion model to simultaneously describe the relative position and attitude. Besides, the Quasi-global positioning system measurement model is used to realize the relative autonomous navigation. Finally, numerical simulations indicate that both models and the relative autonomous navigation algorithm meet the demand of formation flying systems. The results show that models are reasonable and concise and that the algorithm is more efficient.
