A.W. Lyon, U. Guida, J.L. Fernandez, O. Perrin

Abstract:	The EGNOS system has been designed, developed and deployed under a European Space Agency (ESA) contract as part of the ESA ARTES IX programme. The EGNOS system ESA milestone Operational Readiness Review (ORR), which concludes the EGNOS design and deployment activities led by ESA, was completed on June 16, 2005 and was followed by the start of the EGNOS Initial Operations Phase (IOP) on July 27, 2005. A contract has been finalized between ESSP and ESA, to cover the EGNOS Operations Management for the duration of the Initial Operations Phase. EGNOS is planned to be Qualified for Safety of Life use in 2007. This paper addresses: - the activities performed by the Consortium led by ESSP during the EGNOS Initial Operations Phase, where for the first time European Companies are called to manage and operate a wide distributed ground infrastructure for Satellite Navigation; - the services and performances of the Signal in Space today and those expected for the future; - the Mediterranean EGNOS extension; - the EGNOS benefits for the GPS PRN 25 failure analysis on 25th December 2005 and the associated EGNOS reaction.
