ECA GROUP UNVEILS ITS NEW GENERATION MID-SIZE AUV A18-M FOR UNDERWATER MINE WARFARE
On 16th February ECA Group presented its latest mid-size AUV A18-M dedicated to mine counter measures. With its compactness and its unequaled high-quality imagery this new generation underwater drone becomes the reference in the category of autonomous underwater vehicles dedicated to mine hunting. A live demonstration in Toulon area has been conducted in order to show some of the amazing performances of this new maritime drone that is completing ECA Group’s AUV family.
AUV A18-M: compact, modular, connected and enduring
is the new generation of autonomous underwater vehicle developed by ECA Group for efficient mine detection and classification in all water depths up to 300m. Like the and, the AUV A18-M is specifically designed to operate in the close vicinity of the smartest mines without triggering them.
“This mid-size AUV is the top trade-off between, size, weight and long endurance. Its payload capacity makes it able to host high performance sonar, such as synthetic aperture sonar (SAS) providing unprecedented detection and classification performances.” says Léonie Delacou, AUVs product manager at ECA Group.
More compact than previous generation of MCM AUV, is easy to deploy even from small naval platforms such as new generation of . Thanks to its high stability, and the fact that it is less affected by waves than a surface ship or a towed system, a very high image quality is obtained.
In addition, the AUV A18-M can also adapt its operating depth to the environmental conditions, avoiding blind zones due to sound speed stratification.
Advanced embedded processing allows to process in real time the sonar image raw data and extract a list of contacts which are relayed back to the command center using an advanced communication network, with an unmanned surface vessel (USV) or an unmanned aerial vehicle (UAV) acting as gateway. These contacts are then reviewed by sonar operators onboard a mothership or onshore, in order to launch identification and disposal.
An unequaled performance gains with a Synthetic Aperture Sonar (SAS) onboard A18-M
More generally, the AUV is able also to detect any kind of hazard such as improvised explosive devices (IED), pollutants, as well as to provide very accurate maps of the seabed which allow the environment to be assessed with high fidelity.
The AUV integrates the Synthetic Aperture Sonar (SAS) and has very high area coverage rate, of the order of 2km2/hr which represents between 5 and 10 times more than that of a conventional side-looking sonar on an AUV. This optimal configuration enables to cover very large areas – of the order 20-40km2 (depending on transit distance)in a fraction of the time of legacy assets, with far superior image quality, and with reduced risk to personnel.
“The performance gain is due to the very high resolution in both range and cross-range offered by a wideband SAS, of the order of 2.5cm x 3cm constant up to the edges of the swath, which is unachievable, at any practical range, by any other type of sonar on any type of platform. With the only possible exception of buried or concealed mines, all known mines can be detected and high quality classification cues can be extracted from the highlight and shadow structure.” says Dr. Marc Pinto Program Director for Systems of Robots and sonar expert at ECA Group.
