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 ...

Enhancing the Capability of a Ground-Based Optical Telescope for Thai National Space objects Observation ^†

Proceedings, 2020
Nowadays, the space operations environment have to face with space safety problems because of the growing of space debris in resident of space objects (RSOs) that can cause a catastrophic collision. In order to prevent debris-related risks in operational

Light-Curve Classification of Resident Space Objects for Space Situational Awareness: A Scoping Review

Aerospace
The proliferation of Resident Space Objects (RSOs), including satellites, rocket bodies, and debris, poses escalating challenges for Space Situational Awareness (SSA). Optical light curves capture temporal brightness variations influenced by factors such
