European Augmentation Service - a GNSS Monitoring in South Europe Region

In the Civil Aviation field, the international trend (through ICAO, EUROCONTROL) is to adopt one positioning system that allows to follow more flight phases. This will allow to release themselves by ground installations and optimize the traffic flows following the aRea Navigation (RNAV) concept. In order to realize this goal the European Scientific Community is focusing on Augmentation Systems based on Satellite infrastructure (SBAS - Satellite Based Augmentation System) and on Ground based one (GBAS - Ground Based Augmentation System). The goal of this work is to present some results on SBAS and GBAS performances. Regarding SBAS, after the acquisition of a Novatel OEM4 SBAS receiver, the Department of Applied Sciences of Parthenope University created a monitoring station that reflects as much as possible a standardized measure environment for EGNOS Data Collection Network (EDCN), established by Eurocontrol. The Department of Applied Science decided to carry out a own monitoring survey to verify the performance of EGNOS that can be achieved in South Europe region, a zone not fully covered by official (EDCN) monitoring network. Regarding GBAS, starting from a data set of measurements carried out at the GBAS of Milan-Linate airport where we worked on a ground installation (GMS – Ground Monitoring Station) that supervises the GBAS signal and that represents, for our purposes, the Aircraft subsystem. So the set of collected data is to be considered in RTK mode and after the measurements session we processed them with the software PEGASUS v 4.11. Both experiences give us the possibility to evaluate the GNSS1 performance that can be achieved.
