An autonomous optical guidance and navigation strategy in flytng-by small objects

Abstract

Institute of Space and Astronautical Science (ISAS) of Japan Aerospace Exploration Agency (JAXA) is currently planning the missions that the small probe 'intercepter' flybys near-Earth objects. In general, it is impossible to determine the relative orbit during fly-by only with optical information. And usually the optical navigation needs combined with the radio navigation that should provide the relative velocity vector information. This paper first discusses the new integrated guidance and navigation strategy, provided the relative velocity vector between the probe and the object is obtained. And next, paper presents how to obtain full orbit property using the camera and velocity collection information for the guidance. Finally, this paper shows the outline of experiment to verify this strategy. Show more
