GPS "Jamming" in Iraq?

[AlphaOp]

I remember hearing on the news awhile ago that the Iraquis were employing devices to jam GPS signals. (The GPS is now used for both guiding forces and JDAM bombs.) They said they were aquired from the Russians. Did anyone hear about this, or know how these work?

 

I'm thinking that what they might do is simple broadcast on the ground a signal that is the same as that generated by the GPS satellites, which would really screw up GPS units within their broadcasting range. (Some cell phone jammers do a similar thing, making it look like there is a tower nearby, and the cell phone focuses on that, and it doesn't respond.)

According to CENTCOM, all of the GPS jammers that were deployed by Iraq have been destroyed. Apparently the jamming signal they emit can be targeted. One of the jammers was destroyed by a GPS guided bomb (perhaps Saddam should ask for a refund).

There are several sites on the net that have instuctions on how to build your own GPS jammer.

 

Build a battery operated one and put it in a cache.

That was correct, they "jam" the weapon (supposedly) by emitting their own signal on the same frequencies, thereby effectively confusing the processor in the JDAM (or other GPS weapons)with multi-path interference. Two problems....the antenna in a JDAM is in the tail....looking towards the sky as the weapon is falling. Not towards the ground where the jamming signal is coming from. Secondly, the transmitter is easily pointed out with radio frquency tracking equipment, lending itself to easy elimination, if it stays stationary for too long. If it doesn't stay stationary in one place, then it isn't much good that way either, so that is why they were all destroyed so easily. At least that is according to what I read in a U.S. Air Force publication this week.

Great idea. I need one of those for my car so that everyone driving near me can't get a signal. Maybe then the'll hang up and drive.

There's a guy here at Penn State I know. He had a double-locked metal case he had with him one day. He opened it up, and showed me over $5,000 worth of electronics equipment! One WAS a Cell-Phone jammer! He demonstrated it by turning it on, it totally jammed my Cell phone, I couldn't make an outgoing call!

 

I would never use one of those in a public place, though, even if the people were really annoying. It could be an important call you're f-ing with there, you know. (Still, it is tempting. There are those ditzy girls who jabber for mintues at a time into their phones. Plus people who SCREAM into the phones.)

 

Oh yeah, and I think that Jamming cell phones or GPS signals is very illegal.
