So whats your question? Are you just looking for info on what you will need? You'll need a GPS receiver/antenna, a GSM modem, and a microcontroller to decode speed and send to GSM unit.You can take the speed signal from the GPS(which is not very accurate), or you can use the speed sensor on the vehicle or vehicle speed from OBD(some vehicles) or OBD-II(all 1996+).

The speed display on my GPS agrees with the speedometer as close as I can read it, which should be close enuf.
By inaccurate I meant is doesn't react to speed changes very well, It could just be my setup too.
