Abstract

Project Keraunos aims to experiment with a Low-Earth Orbit (LEO) to Ground optical communication link, including turbulence mitigation in the Optical Ground Station (OGS), enabling 10 Gbps or more data rates. Cailabs develops the pilot OGS, equipped with an 80 cm telescope, designed for robust operation under challenging conditions. This paper presents a comprehensive characterization of OGS subsystems, evaluating pointing, acquisition, tracking, beacons, and telecommunication performance with a 2.5 km horizontal link. Initial first light results with the Keraunos satellite are also showcased.
