First On-Orbit Demonstration of a Geospatial Foundation Model
Andrew Du, Roberto Del Prete, Alejandro Mousist +6
Geospatial foundation models (GeoFMs) promise broad generalisation capacity for Earth observation (EO) tasks, particularly under data-limited conditions. However, their large size…
Event-based Star Tracking under Spacecraft Jitter: the e-STURT Dataset
Samya Bagchi, Peter Anastasiou, Matthew Tetlow +2
Jitter degrades a spacecraft's fine-pointing ability required for optical communication, earth observation, and space domain awareness. Development of jitter estimation and compens…
Test-Time Certifiable Self-Supervision to Bridge the Sim2Real Gap in Event-Based Satellite Pose Estimation
Mohsi Jawaid, Rajat Talak, Yasir Latif +2
Deep learning plays a critical role in vision-based satellite pose estimation. However, the scarcity of real data from the space environment means that deep models need to be train…
Event-based Structure-from-Orbit
Ethan Elms, Yasir Latif, Tae Ha Park +1
Event sensors offer high temporal resolution visual sensing, which makes them ideal for perceiving fast visual phenomena without suffering from motion blur. Certain applications in…
High Frequency, High Accuracy Pointing onboard Nanosats using Neuromorphic Event Sensing and Piezoelectric Actuation
Yasir Latif, Peter Anastasiou, Yonhon Ng +5
As satellites become smaller, the ability to maintain stable pointing decreases as external forces acting on the satellite come into play. At the same time, reaction wheels used in…
