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).

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.

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.

• 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

FUNDING

Who is involved in Galileo?

•The European Commission (EC)

•The European GNSS Agency (GSA)

•The European Space Agency (ESA)

INTERNATIONAL INVOLVEMENT

• China (2003)• Israel (2004)• Morocco (2005)• South Korea (2006)• In 2006, Galileo was nationalised.• Norway (2009)• Switzerland (2013)

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.

SATELLITE CONSTELLATION

• 30 Satellites at an altitude of

23 222 kilometers• Three orbital planes

with10 satellites each one.• One satellite spare in

each orbit.• Three orbital planes

are inclined at an angle of 56° to the

equator.
