Abstract

JAXA’s Hayabusa2 is an asteroid sample return mission which achieved two landing operations. To realize autonomous navigation and guidance under uncertain terrain conditions, the spacecraft tracked artificial landmarks called target markers, which the spacecraft deployed towards the surface of the asteroid. We propose a method of estimating the trajectory of the Target Markers using only images and investigate the accuracy and reliability. To determine the relative attitude towards the asteroid surface, we propose an attitude estimation method by using the spacecraft’s own shadow. This paper confirms that the estimated trajectory is sufficiently accurate and the proposed method is a viable option for future missions using artificial landmarks.
