The satellite industry is evolving at a rate not seen in its previous 60 year history. The industry is attracting investment from new players resulting in billions of euros being invested in new space mega constellations. Despite rumours to the contrary, this investment in LEO / MEO systems does not indicate the demise of traditional GEO satellites but is in fact stimulating competition & new technology developments across the whole satellite ecosystem. Traditional GEO satellite operators and manufacturers are now able to capitalize on this growth in the overall industry along with the traditional strengths of the GEO orbit namely reach, broadcasting efficiency and terminal simplicity bringing to market a new generation of GEO flexible software defined satellites. Airbus has always been a leader and innovator in the domain of flexible satellite payload products, and have been designing and building fully flexible digital beam formed active antennas in L band for GEO mobile missions for more than 15 years, using Array Fed Reflector antenna architectures. Based on this heritage and capability Airbus was selected by Eutelsat to design, manufacture, & qualify the Eutelsat Quantum Satellite. Airbus has worked hand in hand with Eutelsat to bring this innovative software defined satellite vision to market and is proud to confirm that the satellite (along with all its supporting operational software) is operating in orbit in full compliance to its requirements and predicted capabilities. The Eutelsat Quantum satellite is the first (to our knowledge) of the new generation of fully flexible Ku band satellites deploying wideband active antennas in transmit and receive frequencies along with flexible channelization and connectivity. This suite of flexible payload technologies provide the satellite with all key aspects of payload flexibility namely coverage, RF power and frequency plan / connectivity. Furthermore, the active antennas also support value added functions such as GEO location, uplink interference management and beam hopping. As such the Eutelsat Quantum Satellite is a trail blazer in being the first to market product in the domain of fully flexible Ku band satellites and is the first to have been launched and successfully tested in orbit. This paper will detail the overall design approach to the Eutelsat Quantum satellite, its game changing overall capabilities, its technical solution and industrial footprint.
