Flight Testing and Data Evaluation of Ground-Based Augmentation Systems

Global Navigation Satellite Systems (GNSS) are becoming an integral part of the navigation structure available to civil aviation. The ground based augmentation system (GBAS) is a practical GNSS application in the aviation community. The ILS-substitute is in the final development phase for CAT I approaches and preparations for certification are in progress. The certification will contain analytical assessments and simulations as well as experiences won by practical applications. In order to contribute to the investigations for a CAT II/III capable GBAS, the DLR (Deutsche Zentrumfur Luft- und Raumfahrt, the national aerospace center) and the Institute of Flight Guidance (IFF) of the Technical University of Braunschweig intend to install a GBAS ground station at the Braunschweig research airport
