The project ROSANNA concept picks up on the conceptual core results of the KOSERNA research project and applies them to specific safety-relevant applications of satellite navigation. The consortium has succeeded in the context of KOSERNA to significantly improve the accuracy and reliability of the positioning with the compact GNSS receiver developed in the precursor KOMPASSION by using a second frequency band (Galileo E5a) and simultaneous evaluation of both polarizations. Moreover, suitable methods for suppression different spoofing signals have been implement. Individual components and algorithms have already been successfully tested in two test fields, the GATE in Berchtesgaden and the ATC in Aldenhoven, in static and dynamic scenarios. The advantages could be convincingly demonstrated on the occasion of the GSA workshop in September 2015 in Aachen. Finally, two promising safety-critical applications have been identified that require highly accurate and robust navigation: the automotive industry, particularly with regard to the importance of satellite navigation for fully automated and driverless driving, maneuvering and transport, and unmanned aerial vehicles (UAV). Both applications have specific challenges that require basic investigation and generate related R & D needs. These tasks are to be worked on and conceptually solved within the framework of the ROSANNA Konzept. In the automotive sector, these include, above all, the development of new vehicle design spaces with simultaneous miniaturization of the antennas and distributed arrangement of small subarrays as well as multi-standard receiver systems (antennas with integrated front-end), which enable the combination of satellite navigation with communication and radar. In the case of UAVs, these are the changing reception characteristics of installed antennas due to the environment, the high agility of the missiles as well as the influence of the rotors and vibrations, eg. of multicopters, on the reception of the navigation signals. In this project, fundamental work for the conception and the assessment of the feasibility is coordinated for both application areas in order to maximize synergies from the expertise available in the consortium.
