Galileo is the European Union's global navigation satellite system (GNSS), crucial for navigation and positioning services. The system has successfully completed its in-orbit validation phase and is transitioning to services delivery, with plans for full operational capability in the near future. The European Space Agency, European Commission, and other stakeholders are ensuring reliable services for users globally.

- 2. 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. 2

- 32. The ITIL Process Model
- 33. 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.
- 35. 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” Service is being re-profiled: Integrity Monitoring Service Provides vital integrity information for life-critical applications 35
