Event-Based Sensor Noise Modeling for Space-Based Space Domain Awareness

The Journal of the astronautical sciences
Building 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.

SSC-KA: A Framework of Space Situational Knowledge Acquisition for Status-Cognition of Satellites

IEEE Access, 2022
With the rapid development of space technology, the environment of the space domain has become more and more complex and changeable, which brought great difficulties in cognition of space domain activity.

Influence of Indirect Solar Irradiance on Satellite Observation

IEEE Access, 2021
With the development of Space Domain Awareness (SDA), satellites’ optical characteristics are becoming attention-grabbing. Sunlight was usually considered the only light source for the satellite observation.

Integrated Space Domain Awareness and Communication System [PDF]

IEEE Vehicular Technology Conference, 2022
Space has been reforming and this evolution brings new threats that, together with technological developments and malicious intent, can pose a major challenge. Space domain awareness (SDA), a new conceptual idea, has come to the forefront.

Event-based sensor multiple hypothesis tracker for space domain awareness [PDF]

, 2022
Event-based cameras are an emerging technology that measure changes in a field of view by recording data for each pixel only when a thresholded change in log-light intensity occurs.
