Abstract:	The EGNOS system is being developed in Europe to provide GPS and GLONASS regional augmentation services to aviation, maritime and land users. EGNOS is a major element of the European Satellite Navigation Program, which is jointly being implemented by the Commission of the European Union, the European Space Agency and EUROCONTROL. It is also the first EUROPEAN step to the GALILEO system. The EGNOS system, as any other Wide Area Augmentation System, relies on the broadcast of correction and integrity information in the pseudo-range domain, which are then used to provide a solution in the position domain service. The objective of this paper is to give a summary of major results achieved in the field of EGNOS System performances qualification. Indeed the final review of EGNOS has been passed in may 2005. System deployment and data collections aiming at demonstrating that EGNOS is compliant to the stringent navigation performance defined by civil aviation standard were completed by that time. This paper contains the main outcomes of the analysis performed on the collected data to verify EGNOS Performance in terms of: Accuracy; Integrity; Continuity; and Availability – Service Area In a second step, this paper highlights the programmatic status of EGNOS and the planned evolution
