Claim 7:
8. The system according to claim 1, wherein the electronic computer is further configured to execute:
acquiring, at each instant tgi of a temporally ordered series of instants {0, tg1, tg2, . . . , tgi−1, tgi, . . . }, a measurement of the position or of the speed of the vehicle carried out by a satellite geolocation unit;
computing, for each instant tgi, a deviation between the measured position or the measured speed acquired at the instant tgi and, respectively, a position or a speed estimated by the integration module for said instant tgi, without taking into account the measurement of the satellite geolocation unit acquired at this instant tgi; then
the correction module correcting, as a function of the deviation computed for the instant tgi, estimated positions and orientations for an instant tk equal or subsequent to the instant tgi, in order to obtain a corrected position and a corrected orientation.
