Abstract
A method for determining the point location of a vehicle stopped on one storage track among a set of storage tracks, using virtual beacons is provided. It determines and compares the likelihood of a plurality of hypotheses as to the stopped location of the vehicle, corresponding to a first set of NBe predefined virtual beacons Be(i), i varying from 1 to NBe, the respective positions of which are known in an amount of one virtual beacon per storage track, by correlating the GNSS geo-positioning signals received at various synchronization reset times of a second set by the GNSS receiver located on board the vehicle with predicted GNSS geo-positioning signals of replicas expected for the various positions of the virtual beacons of the first set at the various times. The detected holding position of the vehicle is the position that corresponds to the maximum likelihood.
