Project Keraunos, funded by French Defense Innovation Agency, aims at experimenting a Low-Earth Orbit (LEO) to ground optical communication (OGS) link with turbulence mitigation in the OGS to be ready for 10 Gbps or more links. Cailabs is developing the OGS for Keraunos with the mindset of realizing the pilot OGS for an industrial product line of turnkey, robust, high throughput and scalable OGS. This pilot OGS, based on a 80 cm telescope, is designed to operate at high data rate (10 Gbps or more), at low elevation and high turbulence, and has been assembled at Cailabs. This paper presents the characterization of all the subsystems of the OGS, in particular evaluation of pointing, acquisition and tracking, beacons and telecommunication subsystems. This characterization is performed on a horizontal link between the OGS and a remote site located 2.5 km away.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ICSOS 2023<\/p>\n","protected":false},"author":2,"parent":0,"template":"","categorie-publication":[99,102],"class_list":["post-3933","publication","type-publication","status-publish","hentry","categorie-publication-aerospatial-et-defense","categorie-publication-communications-laser"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
