Galileo is a planned European system for satellite navigation, which will represent the European version of the American GPS and therefore it could be the first step into the direction of technological independence on the division of satellite navigation. It is to be based on 30 satellites (27 + 3 spares) which are to be 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. Galileo will be capable of providing an optimal covering of the northern European regions and thereby could be a replacement for the GPS, which on his part is currently working with only 24 satellites. The first three Galileo satellites will start in 2006. In 2008 the network with all 30 satellites shall be ready to operate.
