Bertin Technologies delivered to its partner Airbus Defense and Space the focal plane assembly (FPA) of the TELEO payload on-board the BADR-8 geostationary satellite for ArabSat, one of the world’s top satellite operators. TELEO is a new-generation of optical communications technology in space. This payload demonstrator (DM) will enable very high capacity analogue optical feeder link communication. This FPA is intended to be mounted on a telecommunications satellite scheduled for launch in early 2023 and it should have a minimum lifetime of 2 years on a GEO (Geostationnary Orbit) spacecraft, in addition to a several month-orbit rising. Its objective is to establish and maintain a two-way laser communication link with an optical ground station (OGS), for a full-scale proof of concept. This paper will present an overview of the mission, the equipment and its challenges. A focus will be made on part of the alignment process and qualification performed to validate the DM design.
