Any comments? Sad

Bush Prepares for Possible GPS Shutdown

WASHINGTON (AP) - President Bush has ordered plans for temporarily disabling the U.S. network of global positioning satellites during a national crisis to prevent terrorists from using the navigational technology, the White House said Wednesday.

Any shutdown of the network inside the United States would come under only the most remarkable circumstances, said a Bush administration official who spoke to a small group of reporters at the White House on condition of anonymity.

The GPS system is vital to commercial aviation and marine shipping.

The president also instructed the Defense Department to develop plans to disable, in certain areas, an enemy's access to the U.S. navigational satellites and to similar systems operated by others. The European Union is developing a $4.8 billion program, called Galileo.

The military increasingly uses GPS technology to move troops across large areas and direct bombs and missiles. Any government-ordered shutdown or jamming of the GPS satellites would be done in ways to limit disruptions to navigation and related systems outside the affected area, the White House said.

"This is not something you would do lightly,'' said James A. Lewis, director of technology policy for the Washington-based Center for Strategic and International Studies. ``It's clearly a big deal. You have to give them credit for being so open about what they're going to do.''

President Clinton abandoned the practice in May 2000 of deliberately degrading the accuracy of civilian navigation signals, a technique known as "selective availability.''

Right, the GPS system is widely used. Too bad they didn't think of this ahead of time, otherwise whoever started GPS could have put a switch in to switch signal encryption. That way civilian models wouldn't receive a signal. not like anyone couldn't get their hands on a special model anyway.

Now, the question is, how fast can they operate on this? Even if last resort, what would trigger this? You'd need most of the planes int he skies down, most of the boats would h ave to be notified. It'd cause more problems to add on to whatever the terrorists did. Heck, that'd be a great way for the terrorist to make the US weak temporarily. Do something that warrants this where we have to start handling the issues of no GPS navigation.

I like the quote fomr slashdot, "Ironically, this comes alongside the President's plan to strengthen the GPS network against deliberate jamming."
