Galileo, the European global navigation satellite system, is a significant initiative by the EU and ESA, designed to provide advanced navigation services and start delivering early capabilities by the end of 2014. The system includes features such as open services, public regulated services, and search and rescue services, with a structured governance and operational framework in place. As it continues to implement its plan, Galileo aims to enhance its services and meet the needs of EU citizens and stakeholders.

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;
While the system procurement and deployment proceed following
an incremental Implementation Plan, all steps are being taken for
the delivery of Early Services;
After a political decision of Vice-President Antonio Tajani, then
included by President Manuel Barroso in the agenda of the
European Commission, Galileo will start officially delivering Early
Services, i.e. the guaranteed and committed delivery of
capabilities to the community of potential customers/users, as
from the end of 2014.

17. Galileo Early Services: What?
Early services for OS,SAR and PRS will be provided
from 2014
Open Service (OS)
Public Regulated Service
(PRS)
Search and Rescue
Service (SAR)
Commercial Service (CS)
Delivery of a stable signal in space from a
number of satellites in orbit, allowing
ranging interoperable with GPS; time
broadcasting
Delivery of a stable secure signal in
space allowing Pilot Projects with EU
Member States
Guaranteed “forward link” which allows
the detection and localization of distress
signals; validation with Cospas-Sarsat
Initial demonstration projects with
potential service providers
The former “Safety-of-Life” Service
is being re-profiled:
Integrity Monitoring

Provides vital integrity information
for life-critical applications
