Robust Satellite Navigation in Safety-relevant Applications—Concept
The project ROSANNA-concept adopts the core results of the KOSERNA research project and applies them to safety-relevant areas of satellite navigation. Two promising safety-critical applications have been identified that require highly accurate and particularly robust navigation: The automotive sector, especially with regard to fully automated and driverless driving, shunting and transport, as well as unmanned aerial vehicles (UAVs). Both applications pose special challenges that require basic research. These tasks are to be processed and solved conceptually within the framework of ROSANNA-concept. The KN Institute is mainly concerned with the challenges posed by the use of adaptive antennas on UAVs. These include lightweight and compact antenna systems, tracking loops, integration of additional sensors, platform interference and deceptive signals. The project also serves to acquire scientific competence in the field of installed antennas as well as the influence of vibration and rotors and their consideration in beamforming, direction-of-arrival estimation and interference suppression.
In the project ROSANNA-concept, concepts are being developed with which the full functionality of a GNSS receiver (Galileo, GPS, Beidou, etc.) with the interference immunity of a digitally controlled directionally selective array antenna can be implemented in specific safety-relevant applications. The automotive and UAV sectors were identified as such. Both applications pose special challenges that require basic research. In the automotive sector, this primarily includes multi-standard receiver systems (antennas with integrated front end), the combination of various radio services (communication, navigation, radar), as well as the development of new installation spaces on the automobile while at the same time further miniaturizing the antennas and using a distributed arrangement of small subarrays. In UAVs, these are the reception characteristics of installed antennas, the high agility of the flying objects and the influence of rotors and vibrations, e.g. from multicopters, on the reception of navigation signals.
By using an array antenna that can be configured in the digital domain, interference signals emitted intentionally or accidentally can be suppressed. Thus, the availability of navigation signals achieves the robustness against jamming, spoofing and loss of localization, which is required for safety-critical applications as a prerequisite for increasing personal and traffic safety. In this project, fundamental work is carried out on the conception and estimation of feasibility.
