Galileo
The project began in 1999. The funds for the implementation were withdrawn from the support fund, agriculture EU they were issued to a consortium of European companies, which later stated that the system had no commercial prospects.

2023: Europe awarded SpaceX contract to launch Galileo navigation system satellites
On October 23, 2023, it became known that the company SpaceX Elona Musk European Space Agency (ESA) had signed an agreement on the launch of several satellites into orbit. We are talking about spacecraft of the navigation system. Galileo More. here
2019
More than 1 billion smartphones connected to Galileo
In early September 2019, GSA announced that more than 1 billion smartphones were connected to the European satellite navigation system Galileo. At the same time, 156 models of smartphones with Galileo support are available on the market.
The Galileo system is used by governments and civic organizations as a free positioning and navigation service. It is also used in systems such as eCall, a security service that should be used in all European cars released after March 31, 2018.
In the event of an accident, eCall sends an alarm and transmits the exact coordinates of the car to the rescue service. Galileo is also used by search and rescue services. Previously, it took four hours to detect the disaster beacon, and thanks to the Galileo system, this time was reduced to ten minutes by September 2019. The size of the search area was also reduced from ten kilometers to two.
Despite glitches in the summer of 2019, the Galileo system is increasingly popular. Recently, more and more manufacturers of CV equipment have been integrating the ability to receive and process signals from Galileo satellites into their satellite receivers and antennas. This is facilitated by the agreement on compatibility and complementarity with the third generation NAVSTAR GPS system. A full-fledged system with duplication mechanisms and fault tolerance has not yet been launched by September 2019.
The number of smartphone chipsets that are manufactured with Galileo receivers is expected to rise from 1.8 billion in 2019 to 2.7 billion in 2029. The latest launches brought the total number of Galileo satellites in orbit to 26. In all, Galileo is set to have 30 satellites and all launches are expected to be completed by the end of 2020.[1]
26 out of 28 satellites do not work
On July 11, 2019, the Galileo satellite system crashed. Four days later, it was not possible to restore her work.
By 16:00 Moscow time on July 15, 2019, 26 of the 28 Galileo satellites were marked as inoperative, according to the website of the European Agency for Navigation and Satellite Systems (GNSS).
The satellites are down due to a technical incident involving ground infrastructure, according to a statement from European Service Center system operator Galileo. Due to the failure of the system, people cannot use navigation channels from spacecraft.
As a result of the incident, all navigation support was stopped, except for the search and rescue service (SAR), which is used to locate and help people in distress.
 | Users will have difficulty maintaining until the next notice. Signals cannot be used to determine the location, - said in an appeal published on the official website of the navigation system. |  |
According to the authors of the blog InsideGNSS, which monitors the state of the European satellite system, the failure may be due to a malfunction of systems at the exact time center located in Italy.
According to experts, the cause of the malfunctions could be software satellite malfunctions due to an error made during the next update session. ON A few years earlier, such an error led to a network failure. GLONASS
Galileo's "downfall" forced users of the navigation system (government agencies and private companies) to switch to alternative technologies. GNSS says that all Galileo services are experiencing interruptions, so "signals should not be used."[2]
2013
The companies that were part of the consortium did not suffer any punishment for embezzlement, the money was written off. After that, the EU leadership began to again look for material means on Galileo. The price of the project, meanwhile, grew - from 1.1 billion euros, to 3 billion euros, then to 7.7 billion. The last figure for 2013 is 22.2 billion euros.[3]
In 2005, the experimental satellite GIOVE-A was launched, in fact, which is a transmitter with a clock. His task was to occupy the frequencies allocated to the project. In 2008, the second experimental spacecraft of the Galileo system, GIOVE-B, was launched. In October 2011, two satellites went into orbit at once - also "experimental." In October 2012 - two more, and in the same status.
For Galileo until 2020, 6.3 billion euros were allocated within the framework of the seven-year EU budget.
The European Space Agency signed a contract in January 2012 with the French company Arianespace to launch the first 14 satellites of the Galileo navigation system. It will be carried out from the Kourou cosmodrome in South America. Russian Soyuz missiles will be used to deliver the vehicles into orbit. This was reported by MGRK "Mir" with reference to the BBC data.
The launch of 22 satellites has been agreed, but in the future it is planned to bring their number to 30, and by the end of the decade the Galileo satellite system should become a competitor to American GPS and Russian GLONASS. The satellites should be put into orbit by 2020. At the moment, the contract amount is 250 million euros.
Galileo is a joint project of the satellite navigation system of the European Union and the European Space Agency. There are two vehicles in orbit that transmit the signal in test mode. If the tests are successful, then at the end of 2013 two more satellites will be added to them.
European satellites of the Galileo system were in orbit in October 2011, and Russian rocket technologies were also used to deliver them into space. A pair of Galileo satellites were launched into orbit by the Soyuz-ST-B rocket on October 13. The operation took place completely in normal mode and the devices have long begun to carry out their activities. The launch of two European satellites, which became the fifth and sixth, respectively, when creating a new navigation system, took place on August 22, 2014 in French Guiana in South America. The Soyuz-ST-B rocket brought satellites into outer space, but malfunctions in the Fregat-MT upper stage led to a change in the flight path of the vehicles. One of them moved along a trajectory with apogee and perigee indicators of 26 and 14 kilometers, respectively, that is, in an elliptical orbit. Within 17 days of being in space, the European specialists of the space center managed to partially change the orbit, increasing the perigee by 3.5 kilometers and reducing the total elongation of the route. To do this, a total of 11 different maneuvers had to be carried out with the device.
