U.S. May Reduce Non-Military GPS Accuracy

Posted by timothy on from the geocaching-will-be-more-challenging dept.

ward99 writes "The U.S. government may be degrading GPS satellite signals, to cripple Iraqi forces' ability to use those systems during the war. This could potentially reduce accuracy from ~3 meters to over ~100 meters. Users depending on GPS systems may want to do sanity checks on any data returned by those systems during the war. The U.S. will do this by increasing the inaccuracies on the civilian C/A code, turning back on S/A (Selective Availability), by having the satellites deliberately and randomly return inaccurate information on where they are. S/A degrades GPS accuracy to only 100 meters 95 percent of the time and 300 meters the other 5 percent of the time. This will not effect the military P code."

    umm....
    We used your fucked up GPS signals to guide the WMD that you provided all the raw materials for and had provided us in the past.

    Anyonly else ever think of gasing the Iraqi population apart from the UK?

    And then planes will start hitting the tarmac late or early or hitting other things.....they JUST can't do this unplanned. Also, did you think that they terrorists needed a GPS to find the WTC? No they did not. Also, what makes you think that they can't figure out the code or obtain US military hardware?

    Now not only do I have to sit back and watch my government join in on an illegal war. . .

    I'm not attempting to bash or ridicule you. I'm not trying to be confrontational. I'm just curious what a "normal" person thinks (normal being NOT a talking head on TV or in the print media). Why do you (a Brit I'm assuming) think this war is illegal?

    I've tried to talk to a few Europeans (a Brit, two French guys, and a German) about this war, but they were quickly in my face and angry. Then again, we were in a pub... and drinking... alot...

    Bush makes it so easy to bash him.

    Besides, my facts are right--Zuke's figures actually confirm it.
