helo i am developing somekind of GPS tracking system with arduino uno + raspberry pi + modem ZTE i have doing some research and when i found that the system that i built is weak, the hacker can detect even can turn off GPS and GSM signal with jammer
i found that arduino doesnt have the module for anti-jamming, or am i wrong?
if it exists (arduino module for anti jamming) may i know? with tutorial also.
What do you think an 'anti-jamming' module is?
The only way to overcome a jamming device would be to increase the transmission signal strength to overcome the jamming signal. Supposing the jammer is designed to jam standard devices, to overcome it you would have to exceed the standard. You won't find a commercial module to do that, because they would be illegal to use and so there would be no market for them.
If you have control over the receiver and transmitter you can also overcome jamming by coding your signal so that you can correlate to effectively improve S/N. Think CDMA.
However, that does not help with GPS or GSM, other than the fact that this "jammer" is probably illegal and you can get your communication authorities to get them to stop.
And while the attacker may be able to know if you are using GSM, there is no way they can tell if you are using GPS, since you are a passive receiver, unless they pick up your LO.
What is the device with three antennas in the photo ?
I am guessing a multi-band jammer.
Isn't that illegal ?
The best way to help keep a GPS from jamming is to first realize that the GPS signal is below the noise floor and is exploited through coding so any noise in-band will cause problems. I worked on early small UAVs and we used a lot of ripstop nylon that had EMI shielding on it, we would shield the noise emitters and the GPS module seaprately.

i mean some device to make jamming process failed

ok thanks for answer lets say i have this device attached in arduino
and this modem attached
its so hard to control the signal strength with 2 items above, in fact that devices is crucial
if some hacker want to stole my device with jammer, they will do it easily, with only jammer they can steal my device. with only jammer.
raschemmel:
Isn't that illegal ?
yes i know that is illegal,
but they (hackers) who lived in my country always have something illegal to steal something , and this is annoying, i must create a prevention system for it.
What country ?
Its impossible to completely prevent hacking, all you can do is take some measures that make it more difficult.
i.e If the US NSA decide they want to "hack" into your device, they will be able to do it, without you even knowing it happened.
Take a look at this article on Wikipedia Stingray phone tracker - Wikipedia
Albeit that device is supposed to be used by law authorities in the USA... If someone makes it commercially, it can be bought or stolen and used in other countries.

yes but i think its much better that arduino has some hacking prevention system module,
but i think its ok if not, thanks for answer btw.

Something is not adding up here. You are developing a tracking device and you are concerned that someone can "jam" it. You call the alleged jammer a "hacker" and claim they can steal your information. Maybe I am confused here but it is my understanding that hackers usually steal information by intercepting it , not jamming it, and the person using a jammer is using it to prevent the hacker. If your GPS & GSM don't work, all that means is that you can't track. I don't don't see how you get from not being able to track to someone stealing your information. I don't see the connection. There is no such thing as an anti-jamming device because a jammer is a frequency sweeping white noise transmitter that interferes with any signal. The bomb squad use them to prevent terrorists from triggering bombs, particularly bombs with GPS & GSM. It almost sounds like you are a terrorist asking how to build a bomb that can't be jammed by the bomb squad. Can you see how someone might draw that conclusion ?

yeah sorry for misleading, my bad, lets make it clear
yea my system that i have to built is anti theft system, my devices must be put outside and let it be there, if someone want to steal it. the thief will bring the device and take it so far, they will be noticed because the device which being stolen are detected outside of coverage. but if the thief using the jammer (i called em hacker because they can disable all of my system, and they are not just ordinary thief) to steal my device, the device wont be noticed that my device is stolen,
i wont talk so far with terorrist and bomb and NSA or something
but i think i have solved it by myself.
i think i have to seek that devices,
my devices must be put outside and let it be there, if someone want to steal it. the thief will bring the device and take it so far,
The act of doing that is illegal. It is called entrapment.
What country is 62?
yes but i think its much better that arduino has some hacking prevention system module,
No such device exists or can exist, you don't seem to understand the fundamentals of RF. Any transmitter on the same frequency will over ride the signal on your channel.
That video is not in English so I can't make a comment but I would hazard a guess you are either misunderstanding what it shows or it is a fake.
62=indonesia

yea thank u for answer i think i have to seek it by myself
i think i have to seek it by myself
I did say:-
No such device exists or can exist, so seeking it will be fruitless.

how about this thing?

It does not do what you're trying to do.

It is a filter to stop interference from your car's electronics and ignition system from jamming your radio through conducted interference through the power line. It is a low pass filter for your radio's power supply.
As PeterH says it is nothing like what you want.
It looks like you see words but have no idea what they mean.
