A two-way ultrasonic positioning and navigation system and method involve a plurality of objects capable of transmitting and receiving ultrasonic signals. A first object (P) transmits an initiating ultrasonic signal and identifies a second object (111) for responding to the initiating ultrasonic signal. The second object transmits a responding ultrasonic signal after a predetermined time delay from receiving the initiating ultrasonic signal. The first object receives the responding ultrasonic signal, determines a distance between the first object and the second object based on a time period starting at the transmission of the initiating ultrasonic signal and ending at the reception of the responding ultrasonic signal, and on knowledge about the predetermined time delay and other known in advance delays.

L'invention porte sur un procédé et sur un système de navigation et de positionnement ultrasonique bilatéral, ce système comprenant une pluralité d'objets pouvant émettre et recevoir des signaux ultrasoniques. Un premier objet (P) émet un signal ultrasonique déclencheur et identifie un second objet (111) en vue de répondre au signal ultrasonique déclencheur. Le second objet émet un signal ultrasonique de réponse après un retard prédéterminé de réception du signal ultrasonique déclencheur. Le premier objet reçoit le signal ultrasonique de réponse, détermine une distance entre le premier et le second objet sur une durée démarrant à l'émission du signal ultrasonique déclencheur et se terminant à la réception du signal ultrasonique de réponse, et à la connaissance du retard prédéterminé et autres retards connus d'avance.
