Taxonomy for Resident Space Objects in LEO: A Deep Learning Approach

CoRR, 2023
The increasing number of RSOs has raised concerns about the risk of collisions and catastrophic incidents for all direct and indirect users of space. To mitigate this issue, it is essential to have a good understanding of the various RSOs in orbit and their behaviour.

Monocular Relative Pose Estimation Pipeline for Uncooperative Resident Space Objects

Journal of Aerospace Information Systems, 2022
This paper aims to present a deep learning-based pipeline for estimating the pose of an uncooperative target spacecraft from a single grayscale monocular image. The possibility of enabling autonomous vision-based relative navigation in close proximity to a noncooperative resident space object would be especially appealing for mission scenarios such as ...
