Galileo navigation satellite system goes live
<i>The high precision offered by Galileo was one of the reasons why the Pentagon rejected the system in the first place. There were fears that adversaries of NATO or of other allies could use it for military purposes. However, engineers have found a solution to that problem: should a serious crisis arise, the military can jam a certain part of the broadcasting spectrum. This would cut off civilian use, but still retain the functions that are reserved for allied military purposes.</i><p>This seems like quite a big issue; If any of the EU states go to war, then planes and other civilian things relying on Galileo would stop working? Would they fall back to GPS?
