List of Galileo satellites

IOV-1/2(satellites FM-7, 12, 13, 14)first satellite
The first Galileo test satellite, the GIOVE-A, was launched 28 December 2005, while the first satellite to be part of the operational system was launched on 21 October 2011.
This is a list of past and present satellites of the Galileo navigation system.

BeiDou

BeiDou Navigation Satellite SystemBDSBeidou navigation system
The system is intended primarily for civilian use, unlike the more military-oriented systems of the United States (GPS), Russia (GLONASS), and China (BeiDou-1/2).
When fully completed, BeiDou will provide an alternative global navigation satellite system to the United States owned Global Positioning System (GPS), the Russian GLONASS or European Galileo systems and is expected to be more accurate than these.

GLONASS

Global Navigation Satellite SystemGLONASS GPSGLONASS K
The system is intended primarily for civilian use, unlike the more military-oriented systems of the United States (GPS), Russia (GLONASS), and China (BeiDou-1/2). One of the aims of Galileo is to provide an independent high-precision positioning system so European nations do not have to rely on the U.S. GPS, or the Russian GLONASS systems, which could be disabled or degraded by their operators at any time.
Binary offset carrier (BOC) is the modulation used by Galileo, modernized GPS, and BeiDou-2.

Galileo is the global navigation satellite system (GNSS) that went live in 2016, created by the European Union (EU) through the European GNSS Agency (GSA), headquartered in Prague in the Czech Republic, with two ground operations centres, Oberpfaffenhofen near Munich in Germany and Fucino in Italy.
The European Global Navigation Satellite Systems Agency (European GNSS Agency; GSA; formerly European GNSS Supervisory Authority) is the agency of the European Union (EU) that aims to ensure that essential public interests are properly defended and represented in connection with satellite navigation programmes of the union: Galileo and European Geostationary Navigation Overlay Service (EGNOS).

Global Positioning System

The system is intended primarily for civilian use, unlike the more military-oriented systems of the United States (GPS), Russia (GLONASS), and China (BeiDou-1/2). One of the aims of Galileo is to provide an independent high-precision positioning system so European nations do not have to rely on the U.S. GPS, or the Russian GLONASS systems, which could be disabled or degraded by their operators at any time.
There are also the European Union Galileo positioning system, and India's NAVIC.

Binary offset carrier modulation

Binary Offset CarrierBOCBOC(5,2)
In June 2004, in a signed agreement with the United States, the European Union agreed to switch to a modulation known as BOC(1,1) (Binary Offset Carrier 1.1) allowing the coexistence of both GPS and Galileo, and the future combined use of both systems.
It is currently used in the US GPS system, Indian IRNSS system and in Galileo and is a square sub-carrier modulation, where a signal is multiplied by a rectangular sub-carrier of frequency f_{sc} equal or higher to the chip rate.

Prague was selected to host administration of the EU satellite navigation system Galileo.

Soyuz-2

The first two Galileo In-Orbit Validation satellites were launched by Soyuz ST-B flown from Guiana Space Centre on 21 October 2011, and the remaining two on 12 October 2012.
The first launch, from Guiana, was a success (21 October 2011), for the first two Galileo IOV satellites.

European Space Agency

ESAEuropeanEuropean Space Agency (ESA)
In 1999, the different concepts of the three main contributors of ESA (Germany, France and Italy) for Galileo were compared and reduced to one by a joint team of engineers from all three countries.
On certain projects, the EU and ESA co-operate, such as the upcoming Galileo satellite navigation system.

International Cospas-Sarsat Programme

Cospas-SarsatSARSATDistress Alerting Satellite System
Galileo is also to provide a new global search and rescue (SAR) function as part of the MEOSAR system.
MEOSAR consists of SARR transponders aboard the following navigation-satellite constellations: the European Union's Galileo, the Russian Federation's Glonass, and the United States' Global Positioning System (GPS).

The Galileo positioning system is another EU infrastructure project.

Wolfgang Tiefensee

Tiefensee, Wolfgang
German Transport Minister Wolfgang Tiefensee was particularly doubtful about the consortium's ability to end the infighting at a time when only one testbed satellite had been successfully launched.
In 2007, Tiefensee chaired talks following which EU transport ministers agreed unanimously to end talks with a private consortium contracted to develop the Galileo satellite navigation system and to spend €2.4 billion ($3.2 billion) to build it themselves instead.

Italian Space Agency

ASI is a participant in many of ESA's programmes in the field of Earth Observation such as ERS-1, ERS-2, ENVISAT, the Meteosat series and the Galileo satellite navigation system.

In December 2018, British Prime Minister Theresa May announced that the UK would no longer seek to reclaim the investment, and Science Minister Sam Gyimah resigned over the matter.
He said the UK's weakness in the negotiations over the Galileo satellite navigation project was the final straw and he intended to vote against May's deal in the House of Commons on 11 December 2018, and suggested the public should have the right to a final say on the withdrawal agreement in another referendum with the Article 50 process extended.

European Satellite Navigation Industries

Galileo Industries
This project, led by ESA and European Satellite Navigation Industries, has provided industry with fundamental knowledge to develop the mission segment of the Galileo positioning system.
The company was the primary construction company for the Galileo positioning system, tasked with developing and building the satellites and components for the ground segment infrastructure of this satellite navigation system.
