Is there a GPS, or something like that that can either pick up there computers location, or some sort of GPS in their cars, and show it on a map?

there isn't as far as I know, you'd have to attach a tracking unit to a law enforcement vehicle(S)

If there was, you can damn sure bet it was implemented by the government and wouldn't be available for civilian consumption.

That being said, there are computerized trunked radio systems which are being implemented which can provide a rough estimate of where an officer is transmitting from. Very useful if an officer could not be reached via radio for an unknown reason. However, my guess is that's using triangulation from at least three different towers on that particular radio system and not GPS.

Sorry about raing on your parade but its impossible. You can find out distance.

Care to rephrase in English?

Sorry I was using Vista speech recognition.

I said: Sorry to rain on your parade. But by XM frequency strength you can find out there distance if they are using a scanner/trap.

Stfu. Vista only complements your stupidity.


Some departments do have actual GPS receivers that relay their coordinates to a central tracking system(either at the station or dispatch center). With an APCO-25 radio system, they can address select units in close proximity to a given call.

If you call up Sprint and claim to be law enforcement they are able to locate people by the GPS in their phone.
I'm not sure about its use for law enforcement, most likely just the sprint users one by one . Sorry.

If you can find the distance they are from your scanner, then couldn't you theoretically triangulate it and find their location?

You would have to make it your self.

Yes - a few police departments do this to alot of new cadets and their own vehicles to track who is where.. to see who is slacking off and whatever else.. getting access to their network would be the real trick (i am sure the GPS is web based)

finally a helpful acolyte, tell us more

I've thought about this before. I had an idea for an iPhone/ google maps application that would allow users to mark known speed traps and if there is currently a car there. But, it would require a really active user base.

You're just a hair behind things, my friend. (http://www.cnn.com/2008/LIVING/wayoflife/05/30/speed.traps/index.html) Dunno how well it works, and I'm disinclined to try since I've given up cell phones. A scanner with WyoLink programmed in will probably do me just fine here in Wyoming.
