Europe approved funding late last month to launch full development of the Galileo satellite navigation system, which will provide the EU with an alternative to GPS. Go-ahead for Galileo addresses Europe’s concerns that GPS is vulnerable to the wartime whim of its operator, the U.S. Department of Defense. Establishing the system is expected to cost $3 billion and employ 100,000 people. Unlike GPS, Galileo signals will not be free to all users.
