DESCRIPTION
My invited keynote presentation at the International Conference on Localization and GNSS (ICL GNSS 2014), held at Helsinki on 24-26 June 2014.TRANSCRIPT
Galileo, the European GNSS:Status, Challenges and a
Glance at the Future

Summary • EGNOS and Galileo are the key elements of the European
navigation “system of systems”, a strategic and critical infrastructure of the European Union;
• The Galileo global navigation satellite system, joint initiative by the European Union and the European Space Agency, is one of the most ambitious and technologically advanced service systems being developed in Europe, by European industries and with European resources;
• The system procurement and deployment proceed following an incremental Implementation Plan. The In-Orbit Validation phase was concluded last year with very promising results;
• Galileo is entering in its Services Delivery phase, while the system proceeds towards its Full Operational Capability configuration;
• EC, GSA and ESA are presently engineering and developing the organization needed for a continuous and reliable provision of services to EU and worldwide users.

Galileo IOV – Ground Control Centres
© Axel Schultes Architekten
2 Complementary Control Centres:
• Ground Mission Segment (GMS)in Fucino has the responsibilityfor the mission aspects ,
• Ground Control Segment (GCS)in Oberpfaffenhofen, to control and monitor the constellation.
Both centres will be completed to become fully redundant.

Service means Commitment
25
“Je m’engage…”
• By the term “service” we mean the guaranteed and committed delivery of a capability, continued over time, to a community of customers/users.
TECHNOLOGY IS NOT ENOUGH!

The ITIL Process Model
33
Key Performance Indicators (KPIs)• KPIs are tools that may be used by an organization (in
our case, a service enterprise) to define, measure, monitor and track its performance over time toward the achievement of its goals;
• KPIs must be quantitative and quantifiable; • KPIs need to be tailored to the specific organization
priorities and performance criteria. So a service organization, based on a large, complex, high-technology system infrastructure, will look to KPIs that measure areas of performance such as Availability, Continuity, Mean Time to Repair (MTTR), customer satisfaction indices, etc.;
• KPIs are often of statistical nature: they can be evaluated over fixed or rolling time periods.
Galileo Services Roadmap
34
Galileo Early Services: What?Early services for OS,SAR and PRS will be provided
from 2014
Open Service (OS)Delivery of a stable signal in space from a number of satellites in orbit, allowing ranging interoperable with GPS; time broadcasting
Public Regulated Service (PRS)
Delivery of a stable secure signal in space allowing Pilot Projects with EU Member States
Search and Rescue Service (SAR)
Guaranteed “forward link” which allows the detection and localization of distress signals; validation with Cospas-Sarsat
Commercial Service (CS) Initial demonstration projects with potential service providers
The former “Safety-of-Life” Serviceis being re-profiled:
Integrity Monitoring Service
Provides vital integrity information for life-critical applications

Satellites Visibility to Support PVT
