Interoperability of the ENRI GAST-D Ground-Station Prototype with Different Airborne Software Implementations
Ground-based augmentation system (GBAS) interoperability trials were conducted in Ishigaki, Japan in June 2016. The interoperability of different implementations of GBAS airborne equipment/software including the TriPos from TU Braunschweig, a software from ENRI, and the Pegasus software developed by EUROCONTROL were tested with an experimental GAST-D ground prototype developed by ENRI and manufactured by NEC. Some differences were observed in protection levels, likely because of differences in the software tools’ satellite selection strategies. Even so, the position solutions and course deviations were in good agreement between the different implementations, so that interoperability was demonstrated successfully.
