In November 2007, it was agreed to reallocate funds from the EU's agriculture and administration budgets and to soften the tendering process in order to invite more EU companies. In April 2008, the EU transport ministers approved the Galileo Implementation Regulation. This allowed the €3.4 billion to be released from the EU's agriculture and administration budgets to allow
430-450: A general awareness in the commission and elsewhere that it was unlikely that the programme would yield the return on investment that had previously been suggested to investors and decision-makers. On 17 January 2002, a spokesman for the project stated that, as a result of US pressure and economic difficulties, "Galileo is almost dead". A few months later, however, the situation changed dramatically. European Union member states decided it

Should the hydrogen maser encounter any problem, an instantaneous switchover to the rubidium clock would be performed. In case of a failure of the primary hydrogen maser the secondary hydrogen maser could be activated by the ground segment to take over within
688-477: A short circuit in the rubidium clocks and improve the passive hydrogen maser clocks as well on satellites still to be launched. From 11 July till 18 July 2019, the whole constellation experienced an "unexplained" signal outage with all active satellites showing "NOT USABLE" status on the Galileo status page. The cause of the incident was an equipment malfunction in the Galileo ground infrastructure that affected
774-413: A signal-in-space ranging error (SISRE) of 1.6 cm (GPS: 2.3 cm) when using real-time corrections for satellite orbits and clocks. In 1999, the different concepts of the three main contributors of the European Space Agency (ESA) (Germany, France and Italy) for Galileo were compared and reduced to one by a joint team of engineers from all three countries. The first stage of the Galileo programme

The first contract for the launch of Soyuz the CSG was signed at the 2009 Paris Air Show by the Director of the Galileo Programme and Navigation-related Activities René Oosterlinck and a CEO of Arianespace Jean-Yves Le Gall . This contract covered 2 launches of two Galileo satellites each. The contract for the satellites themselves had already been signed by ESA and Galileo Industries in 2006. Launch vehicle components shipped from Saint Petersburg first arrived in French Guiana by ship in November 2009. The Soyuz Launch Site acceptance review took place during

Four of the full operational satellites have each lost at least one clock; but no satellite has lost more than two. The operation has not been affected as each satellite is launched with four clocks (2 PHM and 2 RAFS). The possibility of a systemic flaw is being considered. SpectraTime , the Swiss producer of both on-board clock types, declined to comment. According to ESA , they concluded with their industrial partners for
2322-472: The public-private partnership fell apart, and the European Commission decided to nationalise the Galileo programme. In early 2007, the EU had yet to decide how to pay for the system and the project was said to be "in deep crisis" due to lack of more public funds. German Transport Minister Wolfgang Tiefensee was particularly doubtful about the consortium's ability to end the infighting at
2408-434: The public–private partnership fell apart and the European Commission decided to nationalise Galileo as an EU programme. In November 2006, China opted instead to upgrade BeiDou navigation system, its then-regional satellite navigation system. The decision was due to security concerns and issues with Galileo financing. On 30 November 2007, the 27 member states of the European Union unanimously agreed to move forward with

In August 2018, the UK stated that it would look into creating a competing satellite navigation system to Galileo post-Brexit. 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
2838-634: The European GNSS Service Centre reported the various performance parameters measurements surpassed their target values. Each Galileo satellite has two master passive hydrogen maser atomic clocks and two secondary rubidium atomic clocks which are independent of one other. As precise and stable space-qualified atomic clocks are critical components to any satellite-navigation system, the employed quadruple redundancy keeps Galileo functioning when onboard atomic clocks fail in space. The onboard passive hydrogen maser clocks' precision

Naphthyl is an environmentally safe hydrocarbon fuel with fewer aromatic compounds than kerosene, which also slightly improves engine performance. There are only minor differences in thermal properties, viscosity, and surface tension, so this did not require significant engine changes. Since 2006, Soyuz‑2 rockets have accumulated
3096-673: The Independent Inquiry Board announced the conclusions of its investigation, revealing that a proximity of helium and hydrazine feed lines resulted in a thermal bridge that caused an interruption of propellant supply to the thrusters. Ambiguities in the design documents allowing this to happen were a result of not taking into account thermal transfers in the thermal analyses of the stage system design. The Board recommended 3 corrective actions: Revamping thermal analysis, correcting design documents and modification of manufacture, assembly, integration and inspection procedures of

The first two Galileo In-Orbit Validation satellites were launched by Soyuz ST-B flown from Centre Spatial Guyanais on 21 October 2011, and the remaining two on 12 October 2012. As of 2017, the satellites are fully useful for precise positioning and geodesy with a limited usability in navigation. Twenty-two further satellites with Full Operational Capability (FOC) were on order as of 1 January 2018 . The first four pairs of satellites were launched on 22 August 2014, 27 March 2015, 11 September 2015 and 17 December 2015. In January 2017, news agencies reported that six of

The onboard passive hydrogen maser and rubidium clocks are very stable over a few hours. If they were left to run indefinitely, though, their timekeeping would drift, so they need to be synchronized regularly with a network of even more stable ground-based reference clocks. These include active hydrogen maser clocks and clocks based on

One of the reasons given for developing Galileo as an independent system was that position information from GPS can be made significantly inaccurate by the deliberate application of universal selective availability (SA) by the US military. GPS is widely used worldwide for civilian applications; Galileo's proponents argued that civil infrastructure, including aircraft navigation and landing, should not rely solely upon
5504-532: The period 2014–2020 will be calculated in accordance with the standard formula applied for the Swiss participation in the EU research Framework Programme . In March 2018, the European Commission announced that the United Kingdom may be excluded from parts of the project (especially relating to the secured service (PRS) following its exit from the European Union (EU). As a result, Airbus was to relocate work on
5590-428: The project had run 50% over initial estimates. Galileo is intended to be an EU civilian GNSS that allows all users access to it. Initially GPS reserved the highest quality signal for military use, and the signal available for civilian use was intentionally degraded ( Selective Availability ). This changed with President Bill Clinton signing a policy directive in 1996 to turn off Selective Availability. Since May 2000

This greatly improved the viability of the Galileo project: "The EU's executive had previously said that if agreement was not reached by January 2008, the long-troubled project would essentially be dead". On 3 April 2009, Norway too joined the programme pledging €68.9 million toward development costs and allowing its companies to bid for
5762-460: The propellant line was cooled to below the freezing point of hydrazine. Further investigations were focused on the software error and a means to prevent similar failures in future. Izvestia also reported that the failure of flight VS09 caused a serious reaction in Russian government. Oleg Ostapenko , head of Roscosmos, had a "difficult conversation in the (Moscow) White House". On 7 October 2014,
5848-592: The proposed 18-vehicle constellation. In July 2010, the European Commission estimated further delays and additional costs of the project to grow up to €1.5–1.7 billion, and moved the estimated date of completion to 2018. After completion the system will need to be subsidised by governments at €750 million per year. An additional €1.9 billion was planned to be spent bringing the system up to the full complement of 30 satellites (27 operational + 3 active spares). In December 2010, EU ministers in Brussels voted Prague , in

The €3.4 billion budget for the 2006–2013 period was considered insufficient. In 2010, the think-tank Open Europe estimated the total cost of Galileo from start to 20 years after completion at €22.2 billion, borne entirely by taxpayers. Under the original estimates made in 2000, this cost would have been €7.7 billion, with €2.6 billion borne by taxpayers and
6020-431: The rest by private investors. In November 2009, a ground station for Galileo was inaugurated near Kourou ( French Guiana ). The launch of the first four in-orbit validation (IOV) satellites was planned for the second half of 2011, and the launch of full operational capability (FOC) satellites was planned to start in late 2012. In March 2010, it was verified that the budget for Galileo would only be available to provide

6364-422: The same precision signal has been provided to both civilians and the military. Since Galileo was designed to provide the highest possible precision (greater than GPS) to anyone, the US was concerned that an enemy could use Galileo signals in military strikes against the US and its allies (some weapons like missiles use GNSSs for guidance). The frequency initially chosen for Galileo would have made it impossible for
6450-499: The seventh major version of the Soyuz rocket family . It includes key enhancements over its predecessors, including improved engines along with digital flight control and telemetry systems, enabling launches from fixed platforms and the use of large payload fairings . In its standard configuration, Soyuz‑2 is a three-stage launch vehicle designed for low Earth orbit missions. Notably, its stage numbering differs from some rockets. The boosters are considered its first stage, while
6536-473: The supply lines. In November 2014, ESA announced the satellites would perform a total of 15 orbital maneuvers to raise their perigee to 17,339 km. This would reduce the satellites' exposure to the Van Allen radiation belt , reduce the doppler effect , increase satellite visibility from the ground, and allow the satellites to keep their antennas pointed at Earth during perigee. These orbits would repeat
6622-470: The system. The system uses parallel functioning Precise Timing Facilities in the Fucino and Oberpfaffenhofen Galileo Control Centres, and an issue occurred in Fucino whilst maintenance was performed on the parallel system in Oberpfaffenhofen. In September 2003, China joined the Galileo project. China was to invest €230 million (US$ 302 million, £155 million, CNY 2.34 billion) in the project over
6708-442: The upgraded third stage of the 2.1b to streamline production. These changes slightly enlarged the propellant tanks, enabling longer burn times. The Soyuz‑2.1a conducted its maiden flight on 8 November 2004, launching from Plesetsk Cosmodrome Site 43 with a boilerplate payload simulating a Zenit-8 spy satellite. The Soyuz‑2.1b has all the same features as the Soyuz‑2.1a but uses improved third stage built around
6794-565: The wave of Block IIF satellites launched in 2009, and all subsequent GPS satellites, are stated not to support selective availability. As old satellites are replaced in the GPS Block III programme, selective availability will cease to be an option. The modernisation programme also contains standardised features that allow GPS III and Galileo systems to inter-operate, allowing receivers to be developed to utilise GPS and Galileo together to create an even more accurate GNSS. In June 2004, in
6880-438: The ≤ 30 ns target value. The Signal In Space Error (SISE) was also well within the ≤ 2 m (6 ft 7 in) target value for Single and (more accurate) Dual Frequency receivers. The Galileo navigation message includes the differences between Galileo System Time (GST), UTC and GPS Time (GPST) (to promote interoperability). The Galileo April, May, June 2021 Quarterly Search and Rescue Service Performance Report by
6966-509: Was agreed upon officially on 26 May 2003 by the European Union and the ESA. The system is intended primarily for civilian use, unlike the more military-focused systems of the United States ( GPS ), Russia ( GLONASS ) and China ( BeiDou ) in that Galileo doesn't limit accuracy for non-military applications. The European system could be subject to shutdown for military purposes in extreme circumstances (such as an armed conflict). Italy and Germany are
7052-499: Was important to have a satellite-based positioning and timing infrastructure that the US could not easily turn off in times of political conflict. 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 26 May 2003). The starting cost for the period ending in 2005 is estimated at €1.1 billion. The required satellites (the planned number
7138-764: Was introduced in December 2013. The Soyuz‑2 rocket utilizes the existing facilities of its R-7 derived predecessors, Site 31 at the Baikonur Cosmodrome in Kazakhstan and Site 43 at the Plesetsk Cosmodrome in northwestern Russia. In 2016, additional launch locations opened at Site 1S at the Vostochny Cosmodrome in eastern Russia. The Soyuz‑2 has replaced the Molniya-M , Soyuz-U and Soyuz-FG rockets since 2010, 2017 and 2019 respectively. The key advancement of
7224-479: Was launched 28 December 2005, while the first satellite to be part of the operational system was launched on 21 October 2011. Galileo started offering Early Operational Capability (EOC) on 15 December 2016, providing initial services with a weak signal. In October 2018, four more Galileo satellites were brought online, increasing the number of active satellites to 18. In November 2018, the FCC approved use of Galileo in
7310-536: Was launched in December 2005 and was followed by a second test satellite, GIOVE-B , launched in April 2008. After successful completion of the In-Orbit Validation (IOV) phase, additional satellites were launched. On 30 November 2007, the 27 EU transport ministers involved reached an agreement that Galileo should be operational by 2013, but later press releases suggest it was delayed to 2014. In mid-2006,
7396-438: Was planned for 20 October 2011, however an anomaly was detected in the pneumatic system responsible for disconnecting the fuel lines from Soyuz third stage, forcing the mission to be postponed for 24 hours. On 21 October 2011, at 10:30 UTC, Soyuz ST-B took off for its inaugural, 3 hour 49 minute, flight, making it the first time Soyuz was launched outside of the former Soviet Union territory. On 22 August 2014, Arianespace launched
