  • GPS + cop tracking possible?

    Could anyone translate this site for those who are electrically challenged?

    It sounds like police personnel/Vehicles are trackable by frequency their own radios emit. Is it posible to implement location of cops vehicle with GPS and track them in Star war style with reasonable amount of effort, money and available technology?

    I'm not quite what you are saying.. but I've heard that each cop car broadcasts a radio signal that reaches about 1 mile. And if you had a police scanner tuned to it, you can tell if a cop is close by.

    This is a quote from another forum:
    "I have a Bear Tracker scanner. Not in my current car, don't panic Teutonic Purists. It mounted under the dash and is about the size of a CB radio. I think they have updated and made it much smaller. I automatically scans all normal Police, DOT and Highway Patrol frequencies. It has a special little part that scans only ultra low wavelength repeater transmissions used by Hwy Patrol cars to let you know if you are within one mile of one. They don't even have to transmit for you to pick them up. Pretty cool."

      I'm no expert but I would assume that fundamentaly this is like the radar gun detectors but scanning for their radio signals as opposed to their radar guns. You wouldn't be able to "track them" but you could tell when they were getting close. I imagine the to track them you would need a second scanner at another location and triangulate the position.

        the good part about doing something like this is you can tell when a cop is getting closer.. instead of just there is a cop doing radar somewhere.. plus if your alone going down the road the cop mught gun you and you won't even know he's there tell he locks on.. with this there is no hiding since i think they are required to keep their radios on while on duty

          Did a quick search. It seems pretty pricey, but the " UNIDEN B796D DIGITAL POLICE SCANNER is Computer controllable and programmable ". To what degree, I dont know.

            It is going to be programmable to the point of inputting the frwquencies into it. I don't think its going to have any sort of output to a computer though.

            My bearcat has the Highway patrol warning mentioned earlier. It works pretty good, except for the fact that is god-awfully loud, and scares the **** outta me at high speeds.

            I guess you could rig that LED or the alarm into something monitor by the computer. But I don't think it would be very useful. It just goes off for a little while, then the LED stays on for a little while. And it does get false signals too.

              What about a jammer? I have instructions on how to build one.

                what kind of jammer? radar or laser?

                I have a laser jammer that works well (Escort ZR3).
                But as far as radar jamming goes...wouldnt you need big antennas to get the job accomplished?

                  How the hell would you jam a laser? You'd need some sort of layer of reflective ****e on your car to do that.

                    All you need to do is send out a laser that confuses the cops laser. All it does is make it seem like you are speeding way to fast to be reliable, or too slow to be speeding.

                    Radar jamming is highly illegal. But then again, speeding is illegal too...

                      Oh hell: undercover cops, radars, lasers... It's easier to just commit a cuicide..

                            You've never heard of laser jamming? is way easier and cheaper to do compared to radar jamming. It just involves sending back light waves at the same wavelength of police LIDAR (904 nm). Heres a site that reviewed 6 popular laser jammers: http://www.radartest.com/article.asp?articleID=8502

                              My info will be dated buy I used to install e-911 systems and computer aided dispatch. We had a subcontractor do cappc's and packet radios (this was mid 90's) the cars had IBM thinkpads and would transmit small packets of GPS data and such back to the CAD system. This way when the cop arrived on the scene instead of radioing back they were 10-whatever to the dispatcher they just hit a key on the laptop as they jump out of the car. We had a vehicle status monitor at each cad sation that told the cars location and status and distance to the current 911 call that dispatched had answered. Above we had big viewsonic monitors with a city map and little icons for cop cars and fire trucks would move around the streets. If there was a 911 call a little phone would popup on the map, when the dispatcher changed the status to fire for example the icon would change to a fire, etc. It was fun testing, we could have a couple cops turn off the gps then drive and hide somewhere and turn them back on and we would tell them their location, a big game of hide and seek.
