The Telit GM862-GPS modem module incorporates a 20-channel SiRFstarIII™ GPS receiver, which allows its location to be determined very precisely. If you combine it with an Elektor ATM18 module and install them in your car, you have a tracking device that can send you e-mail or text messages to let you know exactly where your prize vehicle is. That’s handy if you need to lend your car to someone.
