waimate writes "The European Union today decided to go ahead with Galileo, the constellation of 30 satellites which will compete with the U.S. GPS system. The U.S. abolished selective availability three years ago partly to make GPS more useful for all mankind, but also to dissuade other countries from developing their own navigational satellite system, and thus be dependant on the U.S. for both peaceful and military purposes. Since the demise of the Russian GLONASS system, GPS is the only game in town. Evidently recent events make Europe feel less comfortable about such things, and so they're building their own. Good thing for commercialization of space, or bad thing for world peace?"
