This may not help Sadaam, but just in case you're put under GPS surveillance house arrest by an oppressive government, you'll need to learn how to build your own GPS jammer.

  A low cost device to temporarily disable the reception of the civilian
course acquisition (C/A) code used for the standard positioning service
(SPS)[1] on the Global Positioning System (GPS/NAVSTAR) L1 frequency of
1575.42 MHz.

This is accomplished by transmitting a narrowband Gaussian noise signal,
with a deviation of +/- 1.023 MHz, on the L1 GPS frequency itself. This
technique is a little more complicated than a simple continuous wave (CW)
jammer, but tends to be more effective (i.e. harder to filter) against
spread spectrum based radio receivers.

curious. last week I upgraded my Verizon cellphone to a new model. but I didn't know it was a GPS equipped phone until I found small sub head after the model number printed in the manual. actually there were only two point in the manual the word GPS appeared and even no explanation of what GPS was. funny.

in the phone, there is setting for GPS with choices of "911 only" or "always on". but I'm curious if the setting is able to be controled remotely by transponders. heh heh.

If really so, I want to build GPS jammer
or buy it.

I want buy.

Dear sir,

I would like to buy or provide me the circuit diagram of low WIDE BANDWIDTH RANDOM FREQUENCY JAMMER .... 25 mhz to 80 mhz.

I need this ... very urgently !! Please help me ... this frequency normaly for remote control cars !!

Sir,
I just wanna design a frequency jammer with some of the basic components such as a 555 timer and others like transistor and diodes..Can this design ever be accomplished???
Or can the higher frequencies can be jammed by using a technique of harmonics.Which of the two is comparitively easy and less costly???Please do explain...

I am selling some russian made GPS jammer, but they are now cheap at all.

I have one client looking for a full range jammer from 1MHz to 3GHz. IS there any know where I can fine it?

Can you provide me the circuit diagram of low WIDE BANDWIDTH RANDOM FREQUENCY JAMMER .... 25 mhz to 80 mhz... keep getting interference while using remote controlled cars.
Thanks in advance

$DEITY, all of you guys whining and begging are really pathetic.

You want to play around with possibly dangerous technology but are too fucking stupid to use Google.

Please kill yourself now; or at least stay away from anything more technically advanced than a toaster (yes, this includes computers).

Who can provide me the schematic diagram of the GPS jammer? Please send E-mail to :
fgzhao@163.com
Thanks a lot.

can a normal mobile phone be converted to gps reciever??
just by changing software?
else how do you add the hardware?

I thought for a long time about how to make money with GPS jammers, but I came to the conclusion that the Feds would just go nuts over it, especially after 9/11, and anyone selling them -- even if the jammers didn't work that well -- would probably be made an example of.

So, I am in the middle of designing a GPS sniffer -- just sniff out the offending receiver and cover with foil, temporarily remove from vehicle, disconnect from the battery, etc. I finished the PCB design and will building some hardware in the next month or two, but the larger effort is firmware for the TI DSP.

This will detect the leaked local oscillator signal from a distance of 20' to 100'. Retail price should be less than $200.

Dear Sir,

I'm currently working in Australia as a technition for a company. Recently they have installed GPS tracking devices in the cars. On the weekends I found out that the company was spying on us (ie the cars history etc..) I and all the other TECH's are really annoyed about this and would like to get the company back. How can you help?? The tracking devices installed in our cars use GSM technoloy as well as GPS.
