back to article Car thieves making clean getaway with GPS jammers

Car thief gangs have begun using imported GPS jammers to allow them to escape tracking technology. Illicit kit imported into Europe from China operates on the same frequency as GPS satellites to drown out timing signals and confound in-car devices. Because of this in-vehicle systems are unable to either determine their …

    ...yes, hi, I've just had my 60 tonne, 18 wheeler hi-jacked from Clacket Lane Services, it's currently doing 90mph down the southbound M25 between Junctions 5 and 6, registration plate.......sorry? No, I don't have a GPS tracking system."

    what a surprise

    enough said.

    if you invent a way of detecting a crime the crims will invent a way to avoid it.

    It is just surprising it has taken this long. Probably hasn't professional gangs have probably been doing this for sometime.

    Next you'll find the the electronic warfare suppliers can fit a pod to the police choppers to spot a 2W transmitter. All they'll need to do is to remove the automatic targeting and missile delivery system that such toys probably come with as standard.

      GPS jamming detector detectors

      They already exist and many cars already have them. They're called Sat Navs.

      How hard can it be to track a dead spot moving at 70mph along a motorway?

      1. Anonymous Coward

        Very difficult

        Because the only people who'd know it's jammed are the people who're in the next car along. It's not creating a black spot on every Tom Tom in the world or anything.

        And if a 20W would block a river estuary, a couple of mW would block the GPS signals getting to the car's onboard receiver without letting it leak too far outside of the car.

    I've been saying this for the last year..

    Essentially, if you have a car security system that's based on GPS, then you don't really have one at all. These jammers are £30 and very easily available. I bought one just to see what the effect was, and the result was it totally knocked out the GPS of any device I tested with it (iPhone, WM phone, in-car, TomTom), within seconds. Small, plugs into cigarette lighter. Most care thieves will have one, and probably a mobile blocker too.

    Road price charging

    If the UK ever brings in a nationwide road pricing policy, then the sale off such jammers will increase. I think it may be wise to get hold of one now rather than wait until demand rises..

      Sadly the likely government solution will be to assume that you drive from London to Edinburgh every day unless the road charging system shows otherwise, and bill you accordingly. Remember, we're all guilty now unless we can prove we're innocent.

    Transmission power

    If this kit has a high transmission power then it could be used in military applications, a most worrying development as we rely more and more on GPS (or Galileo or GLONASS).

      Wouldn't a powerful transmitter be an advertisment of your position available to anyone who can triangulate the source?

      1. BeefStirFry

        Which is why...

        you only use a small device to knock out a 5m radius, drive to a secluded spot and you have enough time to find the GPS transmitter and put it in the back of another lorry going in the opposite direction...

    So don't have a cigarette lighter socket

    Or have a fake one. Or have no lighter socket but ashtrays, while the villains are still looking for the socket the police arrive... Or have one that switches off after 30 seconds.

    1. Anonymous Coward

      Re:So don't have a cigarette lighter socket

      best would be to have a normal looking cig socket but connected to a hidden inverter that pushes 240V AC down the socket... if their device is fused then the fuse blows, if not.. either the jammer starts smoking or it blows with a loud BOOM!

      Either way, the socket will not be useful for anyone else except yourself and your devices (with a custom-made adapter from cig socket to normal power socket, so that you can power a normal laptop adapter or something else).

    Err...Everyone is missing one MAJOR point

    Tracking devices (at least the one everyones heard of "Tracker") don't just use GPS. In fact GPS is only the secondary method of tracking as it is blocked as soon as the car is crated up....or drives into a multistory. They use VHF and have done since the far it's working quite well.

    1. Anonymous Coward

      VHF Blockers

      This is easliy bypassed by running a low power VHF "frequency inverter" off of the cig lighter socket, using the car's own wiring as the antenna (I saw this once, but didn't think much of it at the time). This usually will encompass the vehicle's tracking antenna and cancel it out. It also utilizes common problems with grounding and proper signal choking off of power leads on post-sale installations.

      This will not work, however, with those that have the antennas mounted on the roof of the car or in the window. Usually easiest to just cut the wire then, eh?

    2. John 48

      Re: Err...Everyone is missing one MAJOR point

      And what do you suppose is being reported over that VHF connection?

      Things like the position of the vehicle obtained from the GPS unit perhaps....

    Disappearing off the radar...

    Amazingly, as soon as you put a tracker car inside a welded steel crate, the signal can't get out. Who would have thought it!

    The words "disappear off the radar" in the original article are really going to get some stupid people jumping to conclusions, and was a very poor choice of phrase. Then again I would expect nothing less from someone who has written a report stating the blindingly obvious. Incidentally, military P-code systems use a different frequency with a much wider signal spread based around a different centre frequency and wouldn't be blocked with these jammers.

    The interesting stuff will be when someone hacks together some FPGA gubbins and a transmitter and generates fake location info. That will really put the cat among the pigeons. It will royally mess up road charging because you could make your car believe it was hundreds of miles away. For that matter you could make other people's cars believe they were in the London charging zone, or suddenly doing 90mph. Sideways.

      or redirect

      The bbc had a similar story on spoofing being feasable today.

      The best use would be to redirect secure vans to dark allyways or even abandened warehouses, the drivers blindly following satnavs, then ... profit

  22. Petrea Mitchell

    Next steps

    Obviously, the solution is to have cars respond to the jammers by immobilizing themselves if they lose their GPS signals.

    Hello, on which planet has this chap been? If you can jam GPS, you can jam GSM/3G too. As a matter of fact, a China made jammer with a reach of a good 20 meters and rechargeable battery costs USD 30. A friend of mine bought one to annoy a sales rep that keeps visiting his hotdesk area :-).

    " that triangulate positions based on the strength of signals from mobile phone masts, or similar technology, needs to be deployed as a complement and backup to GPS-based vehicle tracking and recovery services..."

    Except most of the commercial jammers block both - eg lightinthebox - they are getting really cheap too because there's a mass market for human rights reasons in the far and middle Easts. Cell blocking is equally, if not more, important in these applications.

    2 watts

    "jammer with an output of about 2 watts [can] swamp any signal from the GPS satellites over an area of a few metres.

    You need a jammer of a damn site less than two watts. In fact those of us building radio comms struggle to prevent jamming to co-located gps antennas even when transmitting on a frequency no where near gps frequencies. A bit of intermod products from a couple of transmitters can be enough. A typical gps received signal is so near the noise floor that milliwatts at the right frequency is sufficient at a couple of meters. (bit more difficult with military gps L1/L2 receivers with anti-jam capabilities- but still not that difficult)

  28. Adrian Midgley 1

    strictly, trilaterate, rather than triangulate

    Using the time of flight of the signals and an accurate clock.

    You note that the cell antennas don't swing round like ... well, like old radar dishes or HFDF loops.

    Really, really handy - peace and quiet

    I have one of these jammers hidden in my motorscooter - I use it to stop idiots who drive motorbkies/scooters whilst texting or talking (both illegal here in VietNam).

    The other one, housed in a realistic cell phone case, I use elsewhere such as on public transport WHERE PEOPLE SHOUT. Or in restaurants. Really handy and good for about 50-100 metres.
