Classification of Low Earth Orbit (LEO) Resident Space Objects’ (RSO) Light Curves Using a Support Vector Machine (SVM) and Long Short-Term Memory (LSTM)

Sensors, 2023
Light curves are plots of brightness measured over time. In the field of Space Situational Awareness (SSA), light curves of Resident Space Objects (RSOs) can be utilized to infer information about an RSO such as the type of object, its attitude, and its ...

Automatic maneuver detection and tracking of space objects in optical survey scenarios based on stochastic hybrid systems formulation [PDF]

, 2022
The state space representation of active resident space objects can be posed in the form of a stochastic hybrid system. Satellite maneuvers may be accounted for according to control cost or heuristical considerations, yet it is possible to jointly ...

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 ...
