- Abstract
Global Navigation Satellite System (GNSS) has been applied to all the flight phases of commercial aircraft and expected to be an alternative to VOR/DME and even ILS in near future. PEGASUS (Prototype EGNOS and GBAS Analysfads System Using SAPPHIRE) is a prototype which allows analysis of GNSS data collected from different SBAS (Satelite-Based Augmentation System) and GBAS (Ground-Based Augmentation System). The analysis tool has been developed in the frame of the GNSS-1 operational validation activity defined in the EUROCONTROL SBAS project(EGNOS). Since June 2003 the GBAS Modular Analysis and Research System (MARS) is integrated in PEGASUS in order to support GBAS data processing needs and activities. The GBAS MARS allows to collect and evaluate relevant data and provide required results and is able to assist Air Traffic Service Providers to aid site approval and obtain operational approval of a GBAS installation for supporting CAT-I precision approach conditions at an airport from their respective safety regulation authorities. This paper presents the status of GBAS and SBAS technologies and proposes performance evaluation methods and related analysis results for GNSS using PEGASUS.
