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

Interoperability with GPS
ü Users will be able to use the same receiver to receive both GPS and GALILEO signals
ü 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

EUUS agreement
ü Adoption of a common signal for Galileo L1 and GPS III L1 open signals: BOC(1,1)
ü Adoption of interoperable timing and geodesy standards to facilitate the joint use of Galileo & GPS
ü Broadcast of GPS/Galileo time offset
ü Equivalent protection of Galileo PRS & GPS M Code
ü Nondiscrimination in trade in satellite navigation goods and services
ü Nonrestrictions of access to open service end users

Interoperability with GLONASS
Interoperability is under discussion with Russia
ü Frequency sharing between Galileo E5B and GLONASSL3 gives prospect for interoperability of the two systems
ü Joint broadcasting of GLONASSK/Galileo time offset is seriously envisaged
ü Joint measurement campaign to determine GLONASS/Galileo geodesy transformation parameters

• Last meeting in Dec. 2006 • Program status updates • Technical analyses for compatibility assessment
ü New technical Working Group created on TT&C (Telecommand, Telemetry and Control) coordination
• Subgroup of the Galileo/QZSS Coordination group • 1st meeting hold in March 2007
ü EC/ASBC Meeting in Feb. 2007
• SPAC introduced as the new managing authority for QZSS
• Potential cooperation between the Japanese private sector and the players of the Galileo Project has been discussed (e.g. QZSS could broadcast corrections for Galileo users)

Conclusions
ü 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
ü 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 (20072013)
ü 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
