Satellite Mega Constellations

February, 2021: „Satellite Mega Constellations are the pivotal concept of the “New Space Economy”. They consist of hundreds or thousands of small satellites in a low earth orbit, which is comparable to the orbit of the International Space Station (ISS). The satellites form an information network to deliver new services to end users on the ground including also airborne applications like in-flight entertainment. The by far most important service category of such networks is telecommunications, in particular the delivery of broadband internet services and the connection of sensors and actors in the Internet-of-Things (IoT). In this way, mega constellations are among the key elements of the next generation of telecommunication networks, which is frequently called “6G”. Space borne telecommunication networks are based on an unprecedented variety of technological innovations including radio equipment and signal processing as well as new manufacturing strategies and operational concepts. Moreover, data handling and resource management requires unmatched amounts of automation that is achieved via novel concepts of artificial intelligence. As a consequence, the needed funds to invest into mega constellations are significant and their economic success has not been proven yet. Nonetheless, such constellations offer manifold opportunities for the space industry along the entire value chain, and also end users might benefit from new services such as broadband internet in remote locations or remote autonomous driving. Therefore, on behalf of the German Ministry of Economic Affairs and Energy (BMWi), the Space Administration of the German Aerospace Center (DLR RfM) has awarded a contract to our team to investigate the trends and challenges as well as the opportunities and financial viability of satellite mega constellations for Germany.”

Munich Aerospace Research Group

January, 2021: A new Munich Aerospace research group has been accredited to the Chair of Signal Processing. In cooperation with the DLR Institute of Communications and Navigation (DLR-IKN), this group, entitled „Machine Learning for Network Management and Resource Allocation in Future Satellite Systems“, will focus its research activities on the design of innovative approaches for the operation of complex self-organizing networks. Multi-layered satellite systems will indeed play a major role to guarantee a global connectivity in 5G & Beyond. With flexible digital payloads in different orbits (e.g. LEO, GEO), a high-level of interoperability and reconfigurability will be offered to adapt to varying traffic demands. In this context, machine learning techniques are expected to foster technological breakthroughs.
With this research group, whose scientific and technical management will be taken over by Dr. Thomas Delamotte, Munich Aerospace strengthen the regional expertise on the potential of machine learning solutions in the key area of Aerospace Communications and Navigation. The activities will also allow to address key aspects of the digital transformation of society. To support these efforts, Munich Aerospace will award a PhD scholarship to a talented student who will conduct his research at the Chair of Signal Processing.
