Global Navigation Satellite Systems (GNSS) are already a very important part of aeronautical navigation today and are the fundament of future navigation concepts. With their global coverage and the ability to provide integrity (with and without augmentation systems) they are among the key enablers for advanced air traffic management (ATM) concepts, ensuring that the fast increasing volume of air traffic can be handled efficiently also in the future.
The Augmentation Systems group is conducting research related to different augmentation systems including the Ground Based Augmentation System (GBAS), the Space Based Augmentation Systems (SBAS) and the Advanced Receiver Autonomous Integrity Monitoring (ARAIM) with the focus on aviation sector. The goal is to investigate error sources that can impact the user position, to design integrity monitoring algorithms and develop techniques to detect, mitigate or exclude a faulty element of the system, which could lead to an unacceptable error in the navigation solution.
Our group operates its own GBAS test bed, is regularly conducting flight trials and is actively supporting standardization at institutions such as Eurocae, RTCA and ICAO.
