This paper deals with the autonomous relative navigation of two satellites flying in close proximity. The subject is studied in the framework of a national project financed by the Italian Space Agency to test in space advanced technologies for formation flying and in-orbit servicing missions. Specifically, a small platform will be realized embarking a set of sensors and actuators to safely fly around a larger satellite to carry out a set of experiments ranging from 3D satellite monitoring to autonomous navigation and control. This paper focuses on the proposed navigation algorithm which consists of a real-time Kalman Filter integrating a linearized model of the relative orbital dynamics with the measurement of a stereo-vision system. Navigation system accuracy, effectiveness and robustness are numerically tested considering realistic orbital scenarios.

Abstract

This paper deals with the autonomous relative navigation of two satellites flying in close proximity. The subject is studied in the framework of a national project financed by the Italian Space Agency to test in space advanced technologies for formation flying and in-orbit servicing missions. Specifically, a small platform will be realized embarking a set of sensors and actuators to safely fly around a larger satellite to carry out a set of experiments ranging from 3D satellite monitoring to autonomous navigation and control. This paper focuses on the proposed navigation algorithm which consists of a real-time Kalman Filter integrating a linearized model of the relative orbital dynamics with the measurement of a stereo-vision system. Navigation system accuracy, effectiveness and robustness are numerically tested considering realistic orbital scenarios.
