Geolocation of GSM Mobile devices, even if they do not want to be found. (David Perez, Jose Pico)

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Geolocation of mobile devices (MS) by the network has always been considered of interest, for example, to locate people in distress calling an emergency number, and so the GSM standard provides different location services (LCS), some network-based, and some MS-based or MS-assisted.

OK, but what if a third party, without access to the network, was interested in knowing the exact position of a particular MS? Could he or she locate it?

In this presentation we will show that this is indeed possible, even if the MS does not want to be found, meaning that the device has all its location services deactivated. We will demonstrate a system we designed and built for this purpose, that can be operated in any standard vehicle, and which can pinpoint the exact location of any target MS in a radius of approximately 2 kilometers around the vehicle.

Yet, the main focus of the presentation will not so much be the system itself as it will be the process we followed for its design and implementation. We will describe in detail the many technical difficulties that we encountered along the way and how we tackled them.

We believe this can be useful for people embarquing themselves in similar research projects.

Obviously, a system like this cannot be demonstrated live in the room (it would be quite illegal), but we will show videos of the different consoles of the system, operating in different environments.
