The on board unit

The On Board unit is a universal device that is not tied to a vehicle, vehicle category or driver. The installation into the vehicles is user friendly. It is simply plugged in the standard 12V connection and GPS, GPRS antennas are placed beneath the windscreen. OBU is during driving constantly calculating geostationary position of the vehicle. If vehicle is inside of any the tolling stations OBU sends to Control center demand for charging toll. OBU never sends the data which compromise privacy, such as current or previous positions of the vehicle, the direction of the driving etc.
