    4. EGNOS: GPS augmentation service The European Geostationary Navigation Overlay Service (EGNOS) is Europes first venture into satellite navigation. It augments the two military satellite navigation systems now operating, the US GPS and Russian GLONASS systems, and makes them suitable for safety critical applications such as flying aircraft or navigating ships through narrow channels. Consisting of three geostationary satellites and a network of ground stations, EGNOS achieves its aim by transmitting a signal containing information on the reliability and accuracy of the positioning signals sent out by the Global Positioning System (GPS) and the Global Orbiting Navigation Satellite System (GLONASS). It allows users in Europe and beyond to determine their position to within 2 metres, compared with about 20 metres for GPS and GLONASS alone.

    6. EGNOS Performance (January 2009)

    8. EGNOS Programme Status EGNOS is already broadcasting signals of excellent quality 2009: Assets have been transferred from ESA to the European Community in April 2009 First EGNOS operator contract as of 1st April 2009 New OS ICD release planned for autumn 2009 Lease completed of an EGNOS transponder to replace ARTEMIS as of 2011 Procurement action ongoing for replacement of a 2nd EGNOS transponder Geographical service extension is under study 2010: SOL declaration of "entry into service" planned for mid-2010 (after certification milestone)

    9. EGNOS potential extensions

    10. Service Provision Improvements ?short/medium term Coverage Evolution Eastern Europe, MEDA, Middle East/ACAC ?medium term Africa ?medium/long term Frequency Evolution Extension to the E5a/E5b frequency decided on ARTEMIS replacement Evolution of Standards ?long term Standardisation of E5a and E5b, L1 CBOC on-going Augmentation of new GNSS Additional Services LPV200 service level ?medium term (2011) EGNOS capability to meet this service level currently under technical evaluation EGNOS time service ?medium term Possible critical communication message EGNOS Service Evolutions

    11. EGNOS Value Added

    14. Galileo Implementation Plan GSTB V1 objectives GPS measurements collected world-wide by a network of stations and processed off-line to verify GALILEO Timing, Navigation and Integrity concepts Successful completion in December 2004 with the provision of validated prototype algorithms and models to the Ground Mission Segment IOV Phase CDE1 Contract GSTB V2 objectives Experimental GALILEO Satellite programme Precursor of the IOV Phase Securing GALILEO filings and validating on-board technology in the MEO radiation environment IOV Objectives Verification of all space, ground and user components, including their interfaces, prior to full system deployment Analysis of system performance with the view to refine the FOC system prior to full system deployment Verification of the adequacy of the siting requirements Verification of Navigation Processing Verification of integrity processing regarding the establishment of SISA and IF confidence levels, characterisation of feared events and TTA analysis UERE budget characterisation Deployment risk reduction Verification of operational procedures FOC GSTB V1 objectives GPS measurements collected world-wide by a network of stations and processed off-line to verify GALILEO Timing, Navigation and Integrity concepts Successful completion in December 2004 with the provision of validated prototype algorithms and models to the Ground Mission Segment IOV Phase CDE1 Contract GSTB V2 objectives Experimental GALILEO Satellite programme Precursor of the IOV Phase Securing GALILEO filings and validating on-board technology in the MEO radiation environment IOV Objectives Verification of all space, ground and user components, including their interfaces, prior to full system deployment Analysis of system performance with the view to refine the FOC system prior to full system deployment Verification of the adequacy of the siting requirements Verification of Navigation Processing Verification of integrity processing regarding the establishment of SISA and IF confidence levels, characterisation of feared events and TTA analysis UERE budget characterisation Deployment risk reduction Verification of operational procedures FOC

    15. Galileo Test Satellites Giove-A launched on 28 December 2005 Secured Galileo frequencies Giove-B launched on 27 April 2008 First Passive Hydrogen Maser atomic clock ever flown Implementation of CBOC signal Working as expected

    16. Galileo IOV vs FOC ESA will launch the first four operational satellites using two separate launchers. The first two satellites will be placed in the first orbital plane and the second in the second orbital plane. These four satellites, plus part of the ground segment, will then be used to validate the Galileo system as a whole, using advanced system simulators. Then, the next two satellites will be launched into the third orbital plane. Once the Galileo system has been validated, the final stage will be to build up the rest of the constellation by completing it on all its three orbital planes. This will then require several launches with Ariane-5 or Soyuz from the Europes Space Port in French Guyana. Galileo will then be fully operational, providing its services to a wide variety of users throughout the world. ESA will launch the first four operational satellites using two separate launchers.

    17. IOV Ground Segment Sites

    18. Galileo FOC Procurement Contract notice: 1 July 2008 Infrastructure procurement in 6 work packages Operational Capability in 2013

    19. Galileo Procurement Retained Candidates

    21. EGNOS 2. Galileo 3. EU-USA

    22. EU-USA Common approach with regard to an overall GNSS strategy Solving the compatibility issues and enhancing interoperability Developing a common GNSS standard for Safety of Life Coordinating inputs to UN ICG/Providers Forum

    23. EU-USA Galileo and GPS are compatible and interoperable Thanks to detailed and lengthy bilateral discussions through Working Groups, established by the EU US 2004 Agreement and following close monitoring by the senior levels chaired by US DoS and EC Excellent results to-date MBOC common modulation National Security Compatibility Compliance GGTO implemented on IOV and tested on GIOVE But, many more joint efforts are needed to ensure C&I for all GNSS

    24. GNSS Compatibility & Interoperability

    25. EU-USA Other issues Trade working-group Further definition of non-discriminatory approachto trade in GNSS goods and services (WTO) Discussion on IPR aspects of Galileo R&D Galileo spectrum in U.S. National Table of Frequency Allocations Joint outreach (GPS-Galileo fact sheet etc) Procurement of GPS and Galileo Security Sofar: Export controls, technology control Next: Endorsement of new legal basis for exchange of classified information Protection/hosting of ground stations Security roles and responsibilities

    26. EU-USA Safety of Life Service: common GNSS standard 1st generation SBAS (WAAS EGNOS MSAS GAGAN) has reached a good level of maturity, but are based on GPS only Galileo has designed a SoL standard Integrity concepts likely to evolve with increasing number of constellations Other constellations are interested in developing built-in integrity Users need a single interface, single standard Need common vision for the future
