An ultrasonic signal (106) is used to link a beacon unit ( 101) to a tracker unit (100) to provide a tracking and navigation system for firefighters to use in a smoke filled environment at the scene of a fire. The beacon unit transmits an omnidirectional ultrasonic signal. The tracker unit, using a directional ultrasonic receiver provides a display or other indication of the signal strength of the received signal to allow the direction to the beacon unit to be determined. The ultrasonic signal provided by the beacon unit may be pulse modulated to inlcude digitally encoded data that may be used to identify particular individuals, objects, materials, dangers, or exits. In addition, the tracker unit may be provided with a transmitter and the beacon unit provided with a receiver such that audio communication may be established therebetween.

L'invention concerne un signal ultrasonore (106) reliant une balise (101) à une unité de poursuite (100) pour constituer un système de poursuite et de navigation que les sapeurs pompiers peuvent utiliser dans un environnement enfumé d'un incendie. La balise émet un signal ultrasonore omnidirectionnel. L'unité de poursuite, grâce à un récepteur ultrasonore directionnel, produit un affichage ou autre indication de la force du signal reçu, ce qui permet de déterminer la direction vers la balise. Le signal ultrasonore émis par la balise peut être modulé par impulsion pour comprendre des données codées numériquement pouvant servir à identifier des personnes, des objets, des matériaux, des dangers ou des sorties, en particulier. En outre, on peut doter l'unité de poursuite d'un émetteur et la balise d'un récepteur, établissant ainsi une communication audio entre l'unité de poursuite et la balise.
