It is a system that began to be devised in the mid-90s, when the GPS system was already in orbit and being put into operation, it is simply the European desire to have its own satellite navigation system.

Formerly nobody understood it, now everyone understands it because it is used by all mobile phone applications, it is through navigation systems to be able to have positioning services and know where you are and the exact time. It is a special feature of Galileo, we will also provide added value service, for example we have that are already operational rescue search. Galileo started to provide business administration services and citizens in December 2016, will have full operational capacity in 2020, when its 30 satellites are in orbit.

In the world there are currently 4 satellite navigation systems, the European system, the Galileo system, the GPS system and the United States system is the one that practically for many years has basically been the source of position and time in all receivers and that we all know; Another system is the Russian system, just as GPS was developed during the Cold War era and another system that is under development is the Chinese system..

Until we arrived all the systems were military and the civilian signals had errors of up to 200 meters of accuracy, however little by little in the 90's it was seen that the positioning systems had a long-term future for the civilian population and for that reason Europe was raised to start investing in new technologies, and the European Space Agency began to develop an alternative or complementary program to GPS for Europe to have an autonomous system. The European Commission also decided to invest in this project and funds were collected to carry out the development and global implementation of the system. It was not so much to improve the GPS service, but to democratize navigation in Europe and the world.

Satellite navigation consists of a constellation of 30 satellites that is the case of Galileo orbiting the earth equipped with ultra-precise clocks, these same clocks are those that allow the signals coming from these satellites can communicate with great accuracy the position exact satellite in space and the exact moment when this signal leaves the satellite. The accuracy of Galileo compared to other current systems is going to be better, we are the number one in the world to fly for example hydrogen watches, a very important thing of Galileo is that in addition to being autonomous and independent that was already a goal and in itself, it was developed from the first moment to be interoperable (this means that a receiver at the end can take advantage of all the satellites that it has in view, regardless of whether they are European, Chinese, Russian or American). Galileo is a geostrategic system, for decades we have been dependent on the United States and Russia; the large number of terrestrial systems that depend on satellite navigation, which are a sample of this, energy networks, communication networks, bank transfers, transactions on the stock market.

Anyone who buys a phone in the next few months will automatically have the integrated system, the only thing that users ask once again is accuracy, not only outside the street but also the transfer of the position of being outside or inside the buildings Galileo will also allow opening a range of markets that existed at this time, as autonomous cars in degraded environments or where the accuracy until now was much worse. We are condemned to move the earth is our cradle, we will leave here and satellite navigation and navigation in general has still many terrains to develop and discover.
