Space is key asset for Europe. Europe’s citizens enjoy the benefits, from jobs and economic growth, to public services, efficient communications and security. To respond to global challenges, Europe must continue to have a prominent role in space at a time when other world powers are rapidly developing their space capabilities. Since satellite payload RF components and systems are essential for delivering mission objectives and supporting ground equipment and telecommunication systems, new technologies and techniques are required to respond to emerging satellite applications and technology challenges. To this end, TESLA ETN will create a vibrant, multidisciplinary training-through-research environment uniquely equipped to develop the Advanced Technologies for future European Satellite Applications. It will recruit, train and supervise 15 ESRs, who will collaborate with senior staff in academic and industrial sectors to conduct top-notch research into new and enabling technologies for satellite flexible payloads, big constellation systems and Internet of Space, satellite high-speed communications and remote sensing, as well as large satellite platforms. TESLA will also implement a unique cross-disciplinary and cross-sectorial training program, underpinned by the recent vision for Europe on open innovation, open science and open to the world, with the objectives to train the next generation of creative, entrepreneurial and innovative satellite communication developers, to provide all network ESRs broad training in transferable skills to enhance career perspectives in both the academic and non-academic sectors, to ensure that all network ESRs have the opportunity to complete a full PhD degree program, to enhance the European space economy and business through the provision of highly skilled and mobile researchers, to expose young researchers in extensive public engagement and outreach activities for a wider economic and social impact.
