Abstract
Spacecraft optical navigation can deliver autonomous navigation onboard when Earth-based tracking is saturated, obstructed, or impractical. Optical navigation relies on the correspondences between detected and known or mapped features in imagery to extract position and/or velocity, and data-driven methods, which directly leverage collected data to learn, can improve detection performance. This paper presents an initial data-driven Earth-based detection system using islands as landmarks for the SpaceCraft for Optical- based Position Estimation-1 (SCOPE-1) 3U CubeSat, which will be paired on board with a physics-based estimation framework. The system consists of an island detector trained on Earth observation imagery of islands, an identification procedure to match detected islands to a localized catalog, and a measurement model to estimate spacecraft position. The results indicate that navigation using landmarks with this system is feasible in Low Earth Orbit (LEO).
