Preliminaries of a Space Situational Awareness Ontology [PDF]
CoRR, 2016 Space situational awareness (SSA) is vital for international safety and security, and the future of space travel. By improving SSA data-sharing we improve global SSA. Computational ontology may provide one means toward that goal. This paper develops the ontology of the SSA domain and takes steps in the creation of the space situational awareness ...

On Detecting Deception in Space Situational Awareness [PDF]
Proceedings of the 2021 ACM Asia Conference on Computer and Communications Security, 2021 Space Situational Awareness (SSA) data is critical to the safe piloting of satellites through an ever-growing field of orbital debris. However, measurement complexity means that most satellite operators cannot independently acquire SSA data and must rely on a handful of centralized repositories operated by major space powers.
