I assume that foreign misssiles use GPS to navigate, so this is smart move,
except that Russia also has a GPS system independent of ours. I suspect that
Russia would also shutdown in crisis, leaving aircraft and ships to rely on
their old sextants and RDFs.


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.
