The Galileo positioning system is a proposed satellite navigation system, to be built by the European Union as an alternative to GPS (which is controlled by the United States military) and the Russian GLONASS. The system should be operational by 2010, two years later than originally anticipated. The first stage of the Galileo program was agreed upon officially on May 26, 2003 by the European Union and the European Space Agency (ESA).
It is named after the Italian astronomer Galileo Galilei. The Galileo positioning system should not be referred to as GPS, which refers specifically to the existing United States system, but as "Galileo." Galileo is intended to provide: greater precision to all users, improved coverage of satellite signals at higher latitudes, which northern regions such as Scandinavia will benefit from, a positioning system upon which European nations can rely even in times of war or political disagreement.
