It isa service provided by the US military, and can be withdrawn at any time without notice." True statement. However, the military in the US reports to civiolian leadership, and shutting down GPS access to the civilian world is not something the military would do (even if some general talks about it publicly) without extensively consulting with the White House and Congress. There are too many people with a stake in this to allow such a shut-off to actually happen. In general "can do x without notice" very rarely translates into "will do x without notice," and business people who make decisions about GPS do not worry too much about this. If it ever came up the next attack on Washington would be the Army of Lobbyists crossing the Potomac. There's no known defense for that. 8-) "Wasn't it turned off for a while after Sep 11 (or maybe that was just selective availability)? " There might have been some action taken, but it was limited and short-lived. If you look at the bigger picture, turning off GPS would cost this country a lot more than the attack itself did. There is a parallel in aviation. There were calls from members of Congress after 9/11 to completely ground general aviation in this country for an extended period. If you weren't a military pilot or you weren't an airline captain, you weren't getting off the ground in any way shape or form. And of course Reagan Airport closed down for a while and there was talk of permanently closing it. Both ideas were shot down, thankfully. |
