Abstract

The invention concerns a method for determining the location of a railway vehicle comprising a first navigation module determining a regular resolution position of the railway vehicle with a first accuracy measurement and a second navigation module determining a high resolution position of the railway vehicle with a second accuracy measurement, using the received signals. The method comprises the steps of determining a first confidence area around the regular resolution position, based on the first accuracy measurement, of determining a second confidence area around the high precision position, based on the second accuracy measurement, and of assigning a weight of confidence to the knowing of the actual location of the railway vehicle, by analyzing the overlay of the first and the second confidence areas and the first and the second accuracy measurements.
