Galileo is Europe’s Global Satellite Navigation System (GNSS), providing improved positioning and timing information with significant positive implications for many European services and users.
Galileo represents the European version of the American GPS and therefore it is a step into the direction of technological independence on the division of satellite navigation. It is be based on 30 satellites (27 + 3 spares) which are placed in an elevation of 15.000 miles surrounding the earth on so called Medium Earth Orbits (MEO) and a network of ground stations, which are to control the satellites.
The first three Galileo satellites started in 2011. In 2020 the network with all 30 satellites are up & running.
