On the one hand, Galileo thus ensures European independence from the two military-controlled systems GPS (USA) and GLONASS (Russia), thus underlining Europe’s sovereignty. On the other hand, Galileo not only competes with the two systems, it also complements them. Europe has placed great emphasis on the fact that Galileo will not work against but with GPS. It is based on the same basic technology as GPS, is compatible and, together with GPS, offers significantly higher accuracy as well as increased reliability.
