Abstract
A point location method for a vehicle moving on a constrained trajectory, implemented by a location device comprises tachometry means, odometry means, a group of at least one satellite geopositioning receiver and a time base synchronized to a satellite geopositioning system, the location device detecting the passage of the vehicle closest to a predetermined position by exploiting knowledge of the displacement of the vehicle, by predicting the form of a set of satellite geopositioning signals at the predetermined position and by testing the match between the predicted signals and those received by the group of at least one satellite geopositioning receiver, the displacement of the vehicle being determined from data supplied by the odometry means and a mapping of the trajectory.
