1. A positioning system for use in a vehicle navigation or mapping system, comprising a data store for storing reference sensor measurement data and a processing resource configured to:

  • obtain one or more sets of sensor measurement data from at least one sensor located on or in a vehicle, each set of sensor measurement being indicative of the distance of objects in an environment around the vehicle from the sensor, and each set of sensor measurement data comprising data obtained from a range of positions in a time or distance window along the direction of travel of the vehicle;

    perform a correlation procedure correlating the one or more sets of sensor measurement data with the reference sensor measurement data; and

    determine a relative position of the vehicle against stored location data associated with the stored reference sensor measurement data in dependence on the correlation procedure.
