3. © GMV, 2010 01/10/2010Page 3 GNSS CONTEXT Society, and very specially Europe, depends today very much on GNSS: Obvious for average people: Car navigators, LBS in mobiles… Not so obvious (and more critical): communications network, electrical power supply, economical transactions, transport network (buses, trains…), air navigation, road user charging… Unavailability of GPS can have a very major impact in society, although risk today is extremely small from both technical (more than 20 years of continuous operation) and political reasons (USA commitment + commercial interest) GPS is a very powerful tool for navigation but not enough for civil aviation (very demanding safety and reliability requirements not fulfilled by GPS) EGNOS and Galileo. Characteristics and advantages of European GNSS

4. © GMV, 2010 01/10/2010Page 4 EUROPEAN GNSS STRATEGY In that context, Europe could not remain passive in front of such a strong economical and technological asset and has taken major efforts to develop and operate: Step 1: EGNOS to provide civil and safe complement to GPS. Operational since 1/10/09 Step 1: EGNOS to provide civil and safe complement to GPS. Operational since 1/10/09 Step 2: Galileo is to achieve European sovereignty through dedicated system under civil control Step 2: Galileo is to achieve European sovereignty through dedicated system under civil control EGNOS and Galileo. Characteristics and advantages of European GNSS

5. © GMV, 2010 01/10/2010Page 5 WHAT EGNOS IS Complement to GPS (and GLONASS) to improve overall performances of GPS in Europe and make them compatible with highly demanding Civil Aviation Requirements Signal GPS-like transmitted from geostationary satellites including corrections to GPS and additional integrity information EGNOS Receivers very similar to GPS ones (thanks to signal similarity). Most of GPS receivers today can receive/process EGNOS signals EGNOS and Galileo. Characteristics and advantages of European GNSS

6. © GMV, 2010 01/10/2010Page 6 EGNOS: THE EUROPEAN SBAS EGNOS is the European implementation of SBAS (CA standard) systems. Interoperability ensures that receivers work in any other SBAS EGNOS and Galileo. Characteristics and advantages of European GNSS

8. © GMV, 2010 01/10/2010Page 8 EGNOS ARCHITECTURE (II) EGNOS and Galileo. Characteristics and advantages of European GNSS 47 EGNOS elements deployed onto 41 sites in 22 countries 34xRIMS, 4xMCC, 6xNLES, 3xGEO

9. © GMV, 2010 01/10/2010Page 9 WHAT EGNOS PROVIDES TO USERS Within European Coverage, users (no subject to major local errors) will have: Improved Horizontal and Vertical Accuracy (as compared to GPS). Position Integrity: Provides a bounding of the position errors. This is key for Civil Aviation and the main “differenciator” of EGNOS w.r.t. GPS Continuity and Availability of the service EGNOS and Galileo. Characteristics and advantages of European GNSS

10. © GMV, 2010 01/10/2010Page 10 ACCURACY VS. INTEGRITY EGNOS and Galileo. Characteristics and advantages of European GNSS Integrity concept introduced by civil aviation for those performance affecting safety. E.g. for a safe landing it is not enough that errors are small in average (accuracy); it requires that errors are small all along every landing (integrity). For events for which probability has to be very low, integrity (not accuracy) is the relevant parameter: Landing accident Knife out of the target Wrong detection of zones in RUC High accuracy does not necessarily imply high integrity.

11. © GMV, 2010 01/10/2010Page 11 EGNOS A REALITY TODAY EGNOS in full operation since 1/10/09 Certified service in the very near future Large track of improved performances demonstrated in the last years (EGNOS signal started in 2005) Different users already exploiting the EGNOS service EGNOS and Galileo. Characteristics and advantages of European GNSS

12. © GMV, 2010 01/10/2010Page 12 GALILEO INTRODUCTION Galileo is the second step of the European infrastructure providing a fully autonomous navigation system System “similar” to GPS but with improved performances and additional services Unlike GPS, specially designed for civil use and under civil control Currently under development Two satellites already on orbit EGNOS and Galileo. Characteristics and advantages of European GNSS

13. © GMV, 2010 01/10/2010Page 13 GALILEO SYSTEM: SPACE SEGMENT EGNOS and Galileo. Characteristics and advantages of European GNSS 27 (+3 spares) satellites 3 Orbital planes

15. © GMV, 2010 01/10/2010Page 15 WHAT GALILEO PROVIDES TO USERS As standalone system (see next slide) In combination with GPS: more satellites in direct vision (major advantage for users specially in urban environments) Worldwide coverage EGNOS and Galileo. Characteristics and advantages of European GNSS GPS Galileo

16. © GMV, 2010 01/10/2010Page 16 WHAT GALILEO PROVIDES EGNOS and Galileo. Characteristics and advantages of European GNSS Open Service Commercial Safety of Life Search and Rescue Free to air; Mass market; Simple positioning and timing. Encrypted; High accuracy; Guaranteed service Open Service + Integrity signal Encrypted; Integrity; Continuous availability Near real-time; Precise; Return link feasible Public Regulated Navigation SAR

17. © GMV, 2010 01/10/2010Page 17 CONCLUSION Huge European efforts to provide an advanced GNSS infrastructure in two steps: 1st step (EGNOS) Already operational Substantial performance improvement over Europe Receivers similar to GPS already in the market Free of charge 2nd step (Galileo) Provides European independence Improved performances and additional services worldwide Developed to allow interoperability with GPS: combined use GPS+Galileo of substantial advantage to users EGNOS and Galileo.
