EVent-based Observation of Spacecraft (EVOS): A Neuromorphic Dataset for Spacecraft Proximity Operations

The EVent-based Observation of Spacecraft (EVOS) dataset is designed to support research in event-based vision for autonomous on-orbit inspection and space debris removal. The dataset was collected at Carleton University using the Spacecraft Proximity Operations Testbed (SPOT). The data was captured using an IniVation DVXplorer Micro event camera mounted on a stationary chaser spacecraft platform which observes a moving target spacecraft. The observed target is covered in multi-layer insulation and is equipped with a solar panel and a docking cone. The dataset contains 15 unique experiments, each approximately 300 seconds long, featuring distinct trajectories under different lighting conditions. Time-synchronized ground-truth position and velocity data are provided via a PhaseSpace motion capture system with sub-millimeter accuracy.
