Abstract
A navigation system for an autonomous vehicle (1). It has a lateral row of detectors (2). The ground has discontinuous buried magnetic markers (3) setting up a localized field which in turn produces an induced current which varies in the detectors (2) in dependence on their position. The markers, formed by magnets (151-155) of selected polarity and number, form magnetic signatures which contain items of information for the vehicle. The on-board vehicle computer (1) can deduce its lateral position and the controls to be carried out to accomplish its mission.
