摘要： 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.

摘要： A railway positioning method, based on the movement of a train determined by a signal receiver of a satellite navigation system embedded onboard the train, and on the movement of the train determined by an odometer embedded onboard the train, and a map of the railway tracks, by determination of the ionospheric propagation bias corresponding to a propagation bias of the signal carrier phase of the satellite navigation system, comprises the steps of, by line of sight of the satellites of the navigation system: estimating the biased ionospheric drift by difference between an integrated Doppler term determined by the receiver and a biased estimation of the movement of the train by the odometer; estimating the odometer drift bias and the drift bias of the local clock of the receiver, by least squares resolution of the speed determined by the satellite navigation system, of the drift bias of the local clock of the receiver, and of the odometer drift bias; correcting the estimation of the ionospheric drift, by subtraction of the estimated odometer drift bias; and correcting the integrated Doppler term using the drift bias of the local clock of the receiver and the ionospheric drift bias, and correcting the pseudo-distance deviations using the ionospheric drift bias.

摘要： Methods of checking the integrity of the estimation of the position of a mobile carrier are provided, the position being established by a satellite-based positioning measurement system, the estimation being obtained by the so-called “real time kinematic” procedures. The method verifies that the carrier phase measurement is consistent with the code pseudo-distance measurement. The method comprises a step of calculating the velocity of the carrier, at each observation instant, a step of verifying that at each of the observation instants, the short-term evolution of the carrier phase of the signals received on each of the satellite sight axes is consistent with the calculated velocity and a step of verifying that at each of the observation instants, the filtered position obtained on the basis of the long-term filtered measurements of pseudo-distance through the carrier phase is dependable.
