Abstract
A method for determining the position and orientation of a vehicle includes constructing, for several instants tranging between instants toand to, an estimate of the instantaneous value of the physical quantity on the basis of the measurements of an inertial navigation unit; constructing an estimate of the physical quantity for the instant toby computing the arithmetic mean of the constructed instantaneous values; computing a deviation between a measurement of the physical quantity obtained on the basis of the measurement of an odometer and an estimate of the physical quantity at the instant to; and correcting, as a function of the deviation computed for the instant to, estimated positions and orientations of the vehicle, in order to obtain a corrected position and a corrected orientation.
