Then, it is enabled world wide. Because of the extensive use by the transportation industry of the GPS signal, it is unlikely that this would happen; too many rely on it's high accuracy. Safety would become a real concern.
Item 1: That is correct. Bear in mind that the old military GPS targeting accuracy available to the military was with nuclear weapons being considered... a lot of our hardened silos could withstand a near miss.. with GPS prcision gidance, there would be no such thing as a near miss.. hence the 600 yard offset variance for everything but a USAF GPS reciever. After the collapse of the soviet threat, the offset error mode was switched off.
With a UAV dispersing sarin or anthrax, the 600 yards don't mean toejam. the air-dispersed nature of these chemical materials rely a whole lot less on accuracy than does a nuke trying for a pinpoint hit on a silo door system.
Item 2: The UAV threat is about the worse news i've heard so far. Dispersing nerve agents with a missile or artilley shell can be a lot easier to foil than a UAV. The missile can be intercepted, the artillery site destroyed by counter battery radar controlled fire in moments.
The UAV on the other hand is flying below most military radars, and at too slow a speed to be picked up as a 'threat' by current military radar software algorythms. It is in fact as invisible to our tactical radars as is a stealth fighter to theirs. These things will go unnoticed by all our current detection systems including JStars.
The UAV's will be autonomus.. flying a pre-programed route, without any need for ground control contact. Truly one scary gawddamned threat.
The smaller UAV's the iraqi's have can easily payload 10 pounds with no problem at all over a range of 70 miles, travelling at 50mph with a simple off the shelf israli GPS directed autopilot in place of it's normal GCI gear. 10 lbs of anthrax dispersed over NYC would kill many thousands... and one could easily be launched from say the deck of a freighter 30 miles south of the ambrose light outside of New York harbor.
Fear the UAV's, gents.
