Beschreibung
Zusammenfassung:	The present invention relates to a method and a system for underwater surveillance and monitoring by means of using an autonomous underwater vehicle (AUV), such as inspection of fish farming pens. By using a plurality of external acoustic transmitters the position of the AUV can be determined by using a predefined reference system or dead reckoning. L'invention concerne un procédé et un système destinés à une surveillance subaquatique par mise en oeuvre d'un véhicule subaquatique autonome (AUV), telle que l'inspection d'un enclos de pisciculture. La mise en oeuvre de plusieurs émetteurs acoustiques externes permet de déterminer la position de l'AUV au moyen d'un système de référence prédéfini ou d'un point estimé.
