Posidonia

Overview

Available in two configurations (hull or pole mounted), Posidonia is an ultra-short baseline (USBL) acoustic positioning system dedicated to highly accurate and ultra–long range tracking of subsea vehicles. It offers enhanced performances with a new electronic cabinet (USBL-Box) including the most recent iXblue acoustic signal processing capabilities and full compatibility with Ramses synthetic baseline positioning system.
