Robust Satellite Navigation in security-relevant applications



+49 8153 28 3065



The project ROSANNA builds on the core results of the research project KOSERNA and the concept study ROSANNA Konzept and cuts them down to safety-relevant applications of satellite navigation. The project consortium has succeeded in joint preparatory work to significantly improve the accuracy and reliability of the positioning with the previously developed compact GNSS receiver by using a second frequency band (Galileo E5a) and simultaneous evaluation of both polarizations. Moreover, suitable methods for suppressing various spoofing signal have been implemented. Individual components and algorithms were developed at GATE in Berchtesgaden and the ATC in Aldenhoven which were successfully tested in static and dynamic scenarios and demonstrated on the occasion of a workshop of the GSA. Finally, two promising, safety-critical applications have been identified that require highly accurate and robust navigation: the automotive industry - especially with regard to the importance of satellite navigation for fully automated and driverless driving, maneuvering and transport - and unmanned aerial vehicles (UAVs). Both applications have specific challenges that require basic investigation and generate related R & D needs. For this purpose, promising preliminary studies have been carried out within the scope of the ROSANNA Konzept which are now to be translated into practical designs and suitable demonstrators. In the automotive sector, this includes the development of new installation spaces in automobiles with a distributed arrangement of compact integrated subarrays (antennas with integrated frontend) as well as multi-standard receiver systems, which enable a combination of satellite navigation, in particular with mobile communication (C2X). For UAVs, the challenges are the changes in the reception characteristics of installed antennas due to the environment, the high degree of miniaturization required and the high agility of the aircraft, as well as the influence of rotors and vibrations on the reception of the navigation signals.
