DEVICE AND METHOD FOR ESTIMATING THE LOCATION OF A VEHICLE GUIDED ALONG A CURVILINEAR GUIDE

This relates to a device and method for estimating the location of a guided vehicle along a guide, the device including: an attitude sensor of the guided vehicle providing values of attitude component measurements of the vehicle; a memory for storing virtual attitude beacon data including values of one or more of the attitude components of the virtual attitude beacon and at least one virtual attitude beacon attribute value, including at least one position attribute value of the beacon; and a processor configured to perform an activity of a virtual attitude beacon reader, le virtual attitude beacon reader comparing the stored virtual attitude beacon data and the vehicle attitude measurement values in order to detect an instance of a measurement value of the corresponding attitude component exceeding a value of an attitude component of the virtual attitude beacon data, the attitude component advantageously being the geographic heading.
