The Case
ACSA is the manufacturer of the SeaExplorer glider, an underwater vehicle dedicated to monitoring and collection of environmental data. Since November 2013, the SeaExplorer holds the world record of endurance for multi-sensor UUVs with rechargeable batteries.

The Profile
ACSA, located in the South of France, is a company specialized in underwater robotics and acoustic positioning systems. In 2007, ACSA joined ALCEN Group, which in 2012 recorded sales of $326.5m. Today, ACSA provides both off-the shelf products and on-demand R&D. Its product range includes underwater robotics and positioning systems, led by the SeaExplorer glider. ACSA acoustic positioning GPS systems (GPS Intelligent Buoy) are used to position and track ROVs, divers and AUVs. In addition to physical products, ACSA engineers have an expertise in designing complex underwater systems requiring the following technical skills: acoustics, robotics, electronics, signal processing, hyperbaric mechanics, hydraulics and hydrodynamics.

The Tech
•    ACSA’s SeaExplorer is a glider with an advanced design capable of conducting a variety of long endurance missions. It is a tool that gathers near real-time data for ocean observation and monitoring for scientific, defense and security and offshore applications.

•    The ACSA GIB portable underwater GPS tracking system is in use worldwide to provide positioning and tracking for divers, ROVs, AUVs and submarines. The system provides meter to decimetre accuracies, independent of the location. In addition, real-time D-GPS and depth data can be provided without the use of a dedicated vessel, thereby reducing mission costs considerably.

•    The Detector-1000 is a designed to be an efficient, long range acoustic detection system for locating acoustic pingers.
