5G World Forum – Satellite Technology for the 5G Era

On October 1-2, the IEEE Future Networks Initiative hosted its second 5G World Forum (5GWF) conference in Dresden, Germany. Being the flagship conference of IEEE’s society-overarching initiative on the next generation of mobile communication networks, the 5GWF is among the most important venues to present core technologies and cutting-edge results. For the first time, the event hosted a dedicated workshop on satellite and non-terrestrial networks for 5G. bringing together researchers and practitioners of both ecosystems, the satellite community and the terrestrial mobile network community. This workshop has been organized and led by Prof. Andreas Knopp as its General Chair, and by Dr. Siegbert Martin (CTO of Backnang based TESAT Spacecom GmbH) as well as Dr. Marc Hofmann (program manager for 5G activities in the German Aerospace Center (DLR), Space Administration) as the program co-chairs. With 14 scientific paper presentations, an industry panel discussion, and two major demo cases, the workshop gained enormous interest in both of the addressed communities. Especially the panel, which was organized and vividly moderated by Dr. Marc Hofmann, shed light on different views on the roles and potential contributions of satellite in a 5G ecosystem. Since the panelist came from terrestrial network supplier Ericsson, the satellite MNO SES, the European Space Agency, and the satellite ground equipment supplier Newtec, heterogeneous views on the pros and cons of satellite were lively discussed.

The demo cases performed by our research center covered two important aspects and use cases for satellite in 5G. The first use case, which has been developed and presented by research associate Florian Völk, showed major results of the ESA funded prototyping study SATIS 5. In particular, a mobile 5G edge node (see foto) was set up to present various features where satellite can contribute to the success of 5G for ubiquitous service to everybody. The second use case, which has been developed and presented by Prof. Christian Hofmann, was dedicated to machine-type communications and sensor data transmission in an agricultural context. The demo showed a miniaturized satellite antenna to uplink narrowband sensor information to GEO satellites, relaying this information into a smart farming network. For that purpose, the sensor was equipped with a proprietary waveform developed at our institute that shows unique power efficiency and robustness features for very tight link budgets.

Altogether, the event was extremely valuable and successful to demonstrate and discuss the enormous societal impact that satellite technologies can make when integrated into an upcoming 5G ecosystem. In this context, we were again able to demonstrate and stress our ambition to be among the pioneering institutions for satellite communications technology worldwide.

Tesat Spacecom Science Award 2019

September 11, 2019 Thomas Delamotte, a PhD student of Prof. Andreas Knopp, has received the Tesat Spacecom Science Award 2019 for his PhD thesis entitled „MIMO Feeder Links for Very High Throughput Satellite Systems“. This prize is granted biannually by the market leader in the field of satellite payload equipment, Tesat Spacecom, for scientific innovations with high practical applicability. In his research works, Thomas Delamotte has developed a novel multi-antenna feeder link architecture to address the bandwidth bottleneck encountered in current high throughput systems. To guarantee a high link availability, his solution also includes advanced diversity schemes to mitigate strong rain fades in the frequency bands (e.g. Ka/Q/V-bands) currently used for feeder links operation. The proposed multi-antenna approach represents a serious alternative to other candidates for future system designs such as optical feeder links.

Lecture on satellite broadcasting for elementary school kids

June 22, 2019: A very special audience of 169 elementary school kids, partially accompanied by about 80 parents, enjoyed a university lecture on satellite broadcasting technology last weekend. The lecture was held upon invitation by the county commissioner of the Vogtlandkreis. It was given by Prof. Andreas Knopp and his brother Dr. Marcus Knopp, who is with the German Space Operations Center (GSOC) at German Space Agency (DLR). Starting with the basics of radio waves for information transmission, the lecture explained the purposes of communication satellites as well as the fundamentals of satellite technology, orbit mechanics, and in-orbit transfer of the spacecraft. A lot of experiments were conducted to involve the kids into the lecture. So-called “children’s university” programs have gained high attention in Germany in order to stimulate interests for academic disciplines at early stages of the children’s education already.

SATis5

April 2019 – Satellites will improve 5G systems by making them more agile, smart and robust. Therefore, the role of satellites and non-terrestrial networks needs to be investigated for the provision of the main use case areas of 5G systems. The development of a convergent satellite-terrestrial architecture, tailored to the satellite capabilities and to the targeted use cases is one of the key challenges. The European Space Agency (ESA) funded Demonstrator for Satellite-Terrestrial Integration in the 5G Contex (SATis5) project deals with the key question of the integration of satellites into a large-scale 5G Europe-wide testbed with access to satellite over-the-air demonstration capabilities.
The Chair of Signal Processing hosted the 3rd Milestone meeting of this ESA 5G flagship project on Tuesday 07/05/19. The current status of the testbed development has been presented to the ESA Project Officer Dr. Maria Guta. In addition to the testbed development updates the antenna facilities of the Munich Center for Space Communications which includes the novel antenna site on the UniBw Campus with access to the main satellite frequency bands were presented by the Chair of Signal Processing. The Newtec Dialog Hub platform will be hosted by Mai 20th on the UniBw Campus as one of the main communication nodes of the SATis5 testbed. More or less the complete over the air communication of the SATis5 testbed will be controlled by the Hub platform which is directly connected to our earth station until the end of the project duration in September 2020.

Protecting our Military Satellite Communications

March 2019 – The Chair of Signal Processing supports the Bundeswehr to protect their satellite communication systems. During an over-the-air test using one of the German military communication satellites, Jun.-Prof. Christian Hofmann gave insight into the topic of satellite jamming. The audience was able to see different satellite modem platforms in action with different techniques to increase the robustness against jammers. We were able to show that our test center (SatCERTBw) is able to handle complex over-the-air hardware tests and has outstanding measurement equipment for in-depth hard- and software performance analysis. With this demonstration a major three-years study on protected satellite communication, led by Christian Hofmann, came into its final phase. The study had been awarded to us by the BAAINBw with the aim to prepare the military SATCOM systems for electromagnetic protection in an increasingly complex threat scenario.
