    摘要: A road toll system comprising a vehicle-mounted unit having a satellite navigation receiver (52) implementing a position tracking function. The system further comprises means for determining the routes taken by the vehicle based on the position tracking information and a sensor (54,56,57,58,60,61,62) for detecting a local vehicle condition which is independent of the satellite navigation signals, and which local vehicle condition is dependent on the absolute position of the vehicle or a change in the position of the vehicle. The authenticity of the position tracking information is validated using the sensor information. This system uses a satellite navigation receiver to enable infrastructure-free road tolling to be implemented. The system further provides a way of preventing a so-called fake GPS attack, i.e. providing false GPS data to reduce the road tolls payable. This is achieved by providing validation of the GPS position information by comparing with independent information collected by the vehicle.
