DIY GPS Jammer

Posted on Jun 6, 2012

Hackers listen up. Everyone understands and enjoys the utilitarian benefits that GPS has brought to our lives but what if it didn’t work any more? I suppose you could build some sort of surface to space missile robot that would systematically seek and destroy all the GPS birds in orbit, but that might attract unwanted attention by the authorities. No, your best bet would be to build a little portable device that just affected a small area.

That is exactly what this does. It works by blanketing the GPS L1 frequency (1475.42 MHz) with noise rendering the receiver unable to get an acquisition code. Without one of those it can’t see any satellites. Pretty clever. Now, I have to say that I have no idea if this circuit is going to work, I’ll leave that up to you. I mean, it’s from Phrack magazine after all so that makes it pretty hardcore. Use some common sense in the operation of this device. It might be best used as a conversation starter and that’s all.
