Today we are featuring an article from Phrack – an online hacker magazine. What we have is a do-it-yourself GPS jammer that can have a range of upto several hundred feet. Keep in mind this is not an easy hack – a bachelors in electrical engineering seems like a prerequisite.



    The GPS band pass filter
    is a 2-pole Toko 4DFA-1575B-12 ceramic dielectric filter from Digi-Key[4], part number TKS2609CT-ND. This part is optional, but helps clean up the RF spectrum before further amplification. The filter’s insertion loss is around 2 dB.

    The final RF amplifier is a WJ Communications AH102. It provides another 13 dB of gain, with a higher P1dB compression point of around +27 dBm (500 mW). The AH102 draws the most current of any part, and is not really necessary if you’re aiming for a low range, low current, battery operated device.

This hack is designed to be a low cost one, only using components you can easily find at a trip to Radio Shack. It targets the Global Positioning System (GPS/NAVSTAR) L1 frequency of 1575.42 MHz. Also keep in mind this device will not work against the Russian GLONASS or European Galileo systems.

it would also let somebody home right in on you if they were looking.

goodie, I am a tech level 5 capable of wiring the bashir reactor's safety schematics. rather not, they might get pounded with me in it. too bad WE don't build them any more =(

It also looks like a QED divider, I'll have an equivalent schematic that's simpler soon enough, the divider doesn't get above a couple of Mhz(5.42 I read), wondering what else is connected. If the output is 1.5Ghz like it looks, it would be difficult to get it to work at all.

looks like fun tho
