A method for determining the point location of a vehicle stopped on a holding track among a set of holding tracks, using virtual beacons, the location-determining method being implemented by a system for determining a point location, comprising: - a GNSS receiver, located on board the vehicle, able to directly measure pseudo-distances aligned with a synchronised local time base in a synchronisation imprecision time range, using geo-positioning signals emitted by GNSS geo-positioning satellites visible to said GNSS receiver; and - an electronic processing unit that is external to or integrated into the GNSS receiver, the method for determining a point location comprising a set of steps in which: - the likelihood of several hypotheses as to the determination of the stopped location of the vehicle, corresponding to a first set of an integer number NBe of predetermined virtual beacons Be(i), i varying from 1 to NBe, the respective positions of which are known in an amount of at least one virtual beacon per holding track, is determined (208, 210; 314, 316, 318; 358, 360, 362) and compared by the electronic unit by correlating GNSS geo-positioning signals, received at various instants of a second set by the GNSS receiver located on board the vehicle, with predicted GNSS geo-positioning signals of replicas expected for said various positions of the virtual beacons Be(i) of the first set at the various instants, - the detected holding position of the vehicle is that which corresponds to the maximum likelihood; and wherein, to decrease maladjustment due to a poor synchronisation of the local time reference of the GNSS receiver with respect to the time of the GNSS global positioning system, a coverage of the imprecision time range of the synchronisation of the local clock is ensured by the electronic unit by dividing in a predetermined way said imprecision time range into time segments, respectively represented by synchronization reset instants or times tk, k varying from 1 to Nk, with Nk referring to the number of synchronisation reset instants in the imprecision time range, the correlations of the GNSS geo-positioning signals received by the on-board GNSS receiver being performed at said synchronisation reset times tk. - a GNSS receiver, located on board the vehicle, able to directly measure pseudo-distances aligned with a synchronised local time base in a synchronisation imprecision time range, using geo-positioning signals emitted by GNSS geo-positioning satellites visible to said GNSS receiver; and - an electronic processing unit that is external to or integrated into the GNSS receiver, the method for determining a point location comprising a set of steps in which: - the likelihood of several hypotheses as to the determination of the stopped location of the vehicle, corresponding to a first set of an integer number NBe of predetermined virtual beacons Be(i), i varying from 1 to NBe, the respective positions of which are known in an amount of at least one virtual beacon per holding track, is determined (208, 210; 314, 316, 318; 358, 360, 362) and compared by the electronic unit by correlating GNSS geo-positioning signals, received at various instants of a second set by the GNSS receiver located on board the vehicle, with predicted GNSS geo-positioning signals of replicas expected for said various positions of the virtual beacons Be(i) of the first set at the various instants, - the detected holding position of the vehicle is that which corresponds to the maximum likelihood;
