Temporal Spectrum Analysis for Multi-Constellation Space Domain Awareness
2025 IEEE 36th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC)Space Domain Awareness (SDA) system has different major aspects including continues and robust awareness from the network that is crucial for an efficient control over all actors in space. The observability of the space assets on the other hand requires efficient analysis on when and how observed space objects can be controlled.

Event-Based Sensor Noise Modeling for Space-Based Space Domain Awareness
The Journal of the Astronautical SciencesBuilding off the foundation of a physics-based end-to-end model for event-based vision sensors (EVS) observing resident space objects (RSOs), we apply new techniques to model realistic low-light sensor noise.

The Space Domain Ontologies [PDF]
, 2021 Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and ...
