Multiple Satellite Navigation Systems for the Ground Based Augmentation System

Abstract:	With the modernization of GPS and Glonass and the introduction of Galileo and BeiDou, four Global Navigation Satellite Systems (GNSS) will be available in the future. A combined usage of these constellations results in better performance and availability compared to a single system. For aviation, additional GNSS constellations could be highly beneficial, especially for GNSS based landing systems (GLS) like the Ground Based Augmentation System (GBAS). However, no approval guidelines or certification documents exist for the use of multiple satellite navigation systems in aviation by now. This paper describes an experimental concept to implement Multi-Constellation GBAS with GPS, Glonass and Galileo. Based on some considerations on the underlying data link, experimental Galileo enhancements for GBAS have been defined and implemented in an experimental GBAS simulation. Even though being highly experimental and not specified anywhere, these enhancements allow to perform GBAS simulations (ground & airborne) using multiple constellations. Finally, this concept was verified by flight trials. This paper shows first results of the experimental GBAS processing.
