The central satellite navigation center of the European space agency’s Galileo program will begin full operation on Thursday in Prague’s Holešovice district. The Galileo system or GSA, is the European answer to the American GPS navigation system, and should be launched sometime in 2014 or 2015. The European space agency already has two out of the necessary 18 satellites in orbit and two more should be launched in early October. The central navigation center was originally based in Brussels. The Czech Republic was selected out of 12 EU countries to host the center.
