I was on a cemenary about ppl being threated where a person who helps crime victims told that you can track a person throught the GPS system by checking up his GSM phone.
Is this true???

I don't know what exactly you mean and why you only mention GSM. Technically, I think anything that transmits a signal can be tracked by triangulation. A cellphone for example regardless of carrier can be tracked based on the strength of it's signal as received by the nearby cell sites.

GSM Phones can be tracked as close as 50m -100m in cities and 500-1000m on the country side. But his has nothing to do with GPS, just a combination of triangulation (as mentioned), signal strength and cell-info.
There are location based services which already take advantage of this. For example finding the closest medical center etc.
But this data isn't available to anyone else except carriers and maybe the police on request. |

Maybe @seiunUsagi means configuring a GPS satellite to track down a certain GSM subscriber without using Cell sites as reference. That might be possible if my concept of a GPS system is correct.

Your "concept of a GPS system" is totally incorrect. This is not technically possible.

Ah - maybe he thinks the GPS Satellites actively know the position of each GPS user. That's not true. The system works passively, the GPS receivers "simply" measure the time differences between the signals of more than 3 GPS satellites (very brief and just an analogy).
So the USA don't know the positon of every GPS user, if that was the question.
GSM phones combined with GPS can offer services ON REQUEST of the phone user. Then and only then the GPS position is transmitted.

yes.. it;s the gps module in phones that can be traced, it can also be used to track your kids, peds or whatever. GSM signals however noway reaches into space. They are tracked on the ground by the some goverment institution (like CIA)

companies like sprint offer phones with GPS chips built in, however they aren't for tracking that individual. Like earlier stated GPS is a passive technology. The reason for the GPS chip is so that you can call emergency support and they can know your location to send help, or for the purposes of getting exact directions from an internet map site. The phone is not actively transmitting data on your location. I don't know of any GSM providers in the U.S. that have GPS chips in their phones.
However, with any radio tranceiver device, it is entirely possible to track that device over short distances with triangulation. Just hope nobody is interested enough in you to chase your cell phone signal. |

Why go thro all the trouble of triangulation method and GPS ?
Here's a technique that even you can use to find the location of a person -
first switch on your cell - make sure battery is charged.
Next wait for it to detect the network.
Keep the number of the person you want to track ready.
Then send a txt to that person and ask him where he is ! 
Quite simple aint it ?  |
