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.
