The Resident Space Objects Network: A Complex System Approach for Shaping Space Sustainability [PDF]
The Journal of the Astronautical SciencesNear-Earth space continues to be the focus of critical services and capabilities provided to the society. With the steady increase of space traffic, the number of Resident Space Objects (RSOs) has recently boomed in the context of growing concern due to space debris.

Dealing with nonlinearities in orbit determination of resident space objects
, 2020 Space activities are continuously at risk due to the ever-increasing amount of uncontrolled space objects, called space debris, which can collide with operational spacecraft. Therefore, space agencies have started space situational awareness (SSA) programs, which aim to provide timely and accurate data regarding the space environment and hazards to ...

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.
