Title
(EN) DOPPLER SHIFT NAVIGATION SYSTEM AND METHOD OF USING SAME
(FR) SYSTÈME DE NAVIGATION À DÉCALAGE DOPPLER ET PROCÉDÉ POUR SON UTILISATION
Abstract
(EN)
A device, system and method of use for the relative navigation in a fluid medium, the device having a receiver and a controller, the receiver capable of receiving signals through the fluid medium. The signals, produced by a source, are capable of undergoing Doppler shift, and the controller is capable of determining the Doppler shift of the signals and determining the bearing between the device and the source of the signals. The system further having a first vehicle capable of producing the signals and a second vehicle having the device and wherein the device determines the bearing of the second vehicle in relation to the first vehicle.

L'invention concerne un dispositif, un système et un procédé d’utilisation pour la navigation relative dans un milieu fluide, le dispositif comprenant un récepteur et un moyen de commande, le récepteur étant capable de recevoir des signaux à travers le milieu fluide. Les signaux, produits par une source, sont susceptibles de subir un décalage Doppler, et le moyen de commande est capable de déterminer le décalage Doppler des signaux et de déterminer le relèvement entre le dispositif et la source des signaux. Le système comprend en outre un premier véhicule capable de produire les signaux et un second véhicule doté du dispositif, le dispositif déterminant le relèvement du second véhicule par rapport au premier véhicule.
