Small-body gravity science using compact imaging-lidar devices
Abstract
This paper investigates the usage of range-texture information in lidar images for spacecraft orbit determination around small solar system bodies. In particular, the image co-registration problem with no a-priori knowledge of the observer attitude and position is addressed. A combination of 3D feature-matching and iterative point-cloud alignment techniques is investigated. The fusion of traditional microwave Doppler tracking with lidar image processing in the proposed fashion could pave the way for a new class of gravity science experiments by small satellites.
