SMS based GPS tracker

This is an SMS based GPS tracker using using the Adafruit Ultimate GPS module and the Seeed studio GPRS arduino shield [SIM900 chipset]. The idea of this project is to leverage the free SMS between Virgin mobile prepaid SIM cards in Australia for long distance communication.

Currently the GPRS shield is switched on manually, and should be done about 10 seconds before powering the mbed/GPS in order to disable echo properly during start up. This could easily be fixed by switching the GPRS shield with the mbed at start up, waiting the 10 seconds, set the echo then flush the buffer.

The mbed can read all 160 ASCII chars sent in a message for control.
