The required satellites (the planned number is 30) were to be launched between 20, with the system up and running and under civilian control from 2019. The starting cost for the period ending in 2005 is estimated at €1.1 billion. The European Union and the European Space Agency agreed in March 2002 to fund the project, pending a review in 2003 (which was completed on ). European Union member states decided it was important to have a satellite-based positioning and timing infrastructure that the US could not easily turn off in times of political conflict. Ī few months later, however, the situation changed dramatically. On 17 January 2002, a spokesman for the project stated that, as a result of US pressure and economic difficulties, "Galileo is almost dead". The attention that was brought to this multibillion-euro growing error in sales forecasts resulted in a general awareness in the commission and elsewhere that it was unlikely that the program would yield the return on investment that had previously been suggested to investors and decision-makers. The European Commission had some difficulty funding the project's next stage, after several allegedly "per annum" sales projection graphs for the project were exposed in November 2001 as "cumulative" projections which for each year projected included all previous years of sales. Italy and Germany led the development of the first generation of the Galileo program, while France is playing a more prominent role in the development of the Galileo Second Generation (G2G). The European system will only be subject to shutdown for military purposes in extreme circumstances (such as an armed conflict). The system is intended primarily for civilian use, unlike the more military-oriented systems of the United States ( GPS), Russia ( GLONASS) and China ( BeiDou). The first stage of the Galileo programme was agreed upon officially on by the European Union and the European Space Agency. In 1999, the different concepts of the three main contributors of the ESA (Germany, France and Italy) for Galileo were compared and reduced to one by a joint team of engineers from all three countries. History The headquarters of the EUSPA, which operates the Galileo system, in Prague Main objectives The Galileo system has a greater accuracy than GPS, having an accuracy of less than 1 m when using broadcast ephemeris (GPS: 3 m) and a signal-in-space ranging error (SISRE) of 1.6 cm (GPS: 2.3 cm, GLONASS and BeiDou: 4–6 cm) when using real-time corrections for satellite orbits and clocks. The first pair of FOC satellites are orbiting the Earth in eccentric incorrect orbits whose orientation changes with respect to other Galileo orbital planes. Out of 23 active satellites, three were from the IOV (In-Orbit Validation) types and 20 of the FOC types. The two GIOVE prototype satellites were retired in 2012, one satellite is not available, and four satellites are currently not usable. It is expected that the next generation of satellites will begin to become operational after 2025 to replace older equipment, which can then be used for backup capabilities.Īs of May 2023, there are 23 launched satellites that operate in the constellation.

The full Galileo constellation will consist of 24 active satellites, which is expected by 2021. Galileo started offering Early Operational Capability (EOC) on 15 December 2016, providing initial services with a weak signal, and was expected to reach Full Operational Capability (FOC) in 2022. By July 2018, 26 of the planned 30 active satellites (including spares) were in orbit. 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. Galileo is also to provide a new global search and rescue (SAR) function as part of the MEOSAR system. Galileo is intended to provide horizontal and vertical position measurements within 1 m precision.

A fully encrypted higher-precision service is available for free to government-authorized users. The use of basic (lower-precision) Galileo services is free and open to everyone. One of the aims of Galileo is to provide an independent high-precision positioning system so European political and military authorities do not have to rely on the US GPS, or the Russian GLONASS systems, which could be disabled or degraded by their operators at any time. The €10 billion project is named after the Italian astronomer Galileo Galilei. Galileo is a global navigation satellite system (GNSS) that went live in 2016, created by the European Union through the European Space Agency (ESA), operated by the European Union Agency for the Space Programme (EUSPA), headquartered in Prague, Czechia, with two ground operations centres in Fucino, Italy, and Oberpfaffenhofen, Germany.
