Primi risultati del sistema sperimentale GBAS

The GNSS (Global Navigation Satellite Systems-GPS+GLONASS) are not sufficient to support Air and Maritime Navigation in specific applications; so it is necessary to introduce Augmentation Systems. In last years the European Scientific Community are focusing its attention on Augumentation Systems based on Satellite infrastructure (SBAS - Satellite Based Augmentation System) and on Ground based one (GBAS - Ground Based Augmentation System). This one is a implemented system to support Air Navigation in CAT-I approaching operation. The purpose of this work is to verify GBAS performance. So we started from a data set of measures collected at the GBAS installation of Milano Linate and we process this with the software PEGASUS v 4.0.Some results on availability, integrity and accuracy are reported and discussed.
