GPS Tracking

[Catalin Lungu]

Hi all,
I need to know how it's works gps tracking. I supose that the mobile
device read gps coordinates and send them to an server through gprs.
It's true?

TIA,
Catalin

Correct, but you can change the word gprs to "whatever network interface
that is available (3G, wifi etc.)", - if you are not sending to often or
other network options is not available the system can send the
coordinates by SMS.

You can also track a GPS device my using triangulation, but the
precision is low (but getting better).
