GPS tracker unit Bit 1C Ltd is a New Zealand based company looking for a device to provide tracking data for a new tracking application. The application requires a device that can be permanently installed in a wide variety of vehicles. The device needs to collect position data from the GPS and relay this back to a server on the internet using GPRS. Ideally the unit will have a small footprint (100mm x 55mm x 10mm). I have outlined features that are required and features that would be desirable.  Required Features: Must accept 12-14v DC Must be GSM/GPRS Must be able to send position updates via either TCP, UDP or HTTP (GPRS) Desirable Features (not required): Run on 9v-36v DC Low power consumption Quad band GSM at least 12 channel GPS Know when the vehicle ignition is off so it can go into a standby mode SMS support (poll device via sms for position) be able to Poll via GPRS Variable position reports (change in speed bearing etc) Included GPS Antenna Included GSM Antenna Additional IO Ports Relay Control  Alarm inputs
