The European Approach Step 1: EGNOS to provide civil complement to the military GPS (and GLONASS), into operations in 2005 EGNOS is an initiative of the European Commission, Eurocontrol and ESA Step 2: GALILEO is to achieve European sovereignty and service guarantees through a dedicated system under civil control. GALILEO is an initiative of the European Commission and ESA 3

Interoperability with GPS Users will be able to use the same receiver to receive both GPS and GALILEO signals The availability of two or more constellations, more than doubling the total number of available satellites, will enhance the quality of the services, increasing the number of potential users and applications Improved accuracy (better geometry, ) Optimum integrity (Galileo integrity, redundancy, ) Increased availability (urban canyons, buildings, ): GPS in cities: 50 % availability Galileo + GPS in cities: 95 % availability 6
EU US agreement Adoption of a common signal for Galileo L1 and GPS III L1 open signals: BOC(1,1) Adoption of interoperable timing and geodesy standards to facilitate the joint use of Galileo & GPS Broadcast of GPS/Galileo time offset Equivalent protection of Galileo PRS & GPS M Code Non discrimination in trade in satellite navigation goods and services Non restrictions of access to open service endusers 7
Interoperability with GLONASS Interoperability is under discussion with Russia Frequency sharing between Galileo E5B and GLONASS L3 gives prospect for interoperability of the two systems Joint broadcasting of GLONASS K/Galileo time offset is seriously envisaged Joint measurement campaign to determine GLONASS/Galileo geodesy transformation parameters 8

Galileo Implementation Logic 2003 2005 2009 2011 2012 Definition Phase Completed in 2003 Under responsibility of: STEP1 STEP2 STEP3 STEP4 ESA Concessionaire GNSS European Programmes managed by the GSA 18
GIOVE A Constructed by SSTL, UK Lift off mass: 600 kg Power demand: 700 W Stowed Dimensions: 1.3 m x 1.8 m x 1.6 m GIOVE A is Europe s first satellite placed in a medium Earth orbit Launched on 28 December 2005 The GIOVE A satellite: Transmits the Galileo signals Tests critical technologies (e.g. rubidium atomic clock, signal generator) Measures environment for future constellation 19
GIOVE A2 GIOVE A2 ordered in March 2007 The GIOVE A2 satellite will: Secure the presence of a spacecraft in orbit Continue the successful experiments initiated with GIOVE A Reinforce the monitoring of the space environment Generate additional signals to provide early in orbit experimentation with the EU/US L1 OS common baseline 20
GIOVE B Constructed by Galileo Industries Lift off mass: 485 kg Power demand: 940 W Stowed Dimensions: 1 m x 1 m x 2.4 m The GIOVE B satellite will: Transmit the Galileo signals Test critical technologies: passive hydrogen maser clock, rubidium atomic, signal generator Measure environment for future constellation GIOVE B is expected to be launched by November 2007 21

Conclusions Galileo is representative of the Political ambition of Europe Independence and sovereignty 27 EU Member States supporting the Programme Safety and Security Economic & Social perspectives Not only a unique reference for the construction and cohesion of Europe, Galileo is a leverage for international cooperation. International cooperation is one of the major objectives of European Commission 7 th Framework Programme (2007 2013) Technical coordination with QZSS is ongoing. Discussions on potential ways of cooperation between the Japanese private sector and the players of the Galileo Project has been initiated 34
