3. WHAT IS GALILEO?
Galileo is the global
navigation satellite
system that is currently
being created by
the European Union (EU)
and the European Space
Agency (ESA).
4. WHY EUROPE NEEDS GALILEO
• The system will be under civilian control and its
coming online will allow positions to be
determined accurately for most places on Earth.
• With Galileo, Europe will be able to exploit the
opportunities provided by satellite navigation to
the full extent.
•Receiver and equipment manufacturers,
application providers and service operators will
benefit from novel business opportunities.
5. OBJECTIVES
• The 30-satellite Galileo navigation system will
provide high-quality positioning, navigation and
timing services to users across the whole world
as a civil-controlled service.
• In-Orbit Validation’s phase aims to perform an in-
orbit validation of the system using a reduced
constellation of four Galileo In-Orbit Validation
satellites.
6. • The four satellites perform a dual role, serving
as a validation of the overall Galileo system
while also being part the operational Galileo
constellation – each IOV satellite being designed
for a full 12-year lifespan providing navigation
services to users worldwide.
• The results will be crucial to Galileo’s success,
used to set benchmarks for their operational life
and used as a reference across the entire
Galileo constellation.
OBJECTIVES
7. FUNDING
Who is involved in Galileo?
•The European Commission (EC)
•The European GNSS Agency (GSA)
•The European Space Agency (ESA)
8. INTERNATIONAL INVOLVEMENT
• China (2003)
• Israel (2004)
• Morocco (2005)
• South Korea (2006)
• In 2006, Galileo was nationalised.
• Norway (2009)
• Switzerland (2013)
9. POLITICAL INVOLVEMENT
• Galileo provides access to all
users with high precision
signals, whereas GPS
provides the highest precision
to military users.
• The US was concerned that
an enemy could use Galileo
signals in military strikes
against the US.
• The EU and the US signed an
agreement.
10. SATELLITE CONSTELLATION
• 30 Satellites at an
altitude of
23 222 kilometers
• Three orbital planes
with
10 satellites each one.
• One satellite spare in
each orbit.
• Three orbital planes
are inclined at an
angle of 56° to the
equator.
