Description

The ASEMAR autonomous unmanned vehicle for maritime surveillance and security is a project funded by the General Directorate for Enterprises (DGE) in France and involves several partners. The two main companies are Thales and ECA ROBOTICS and four educational institutions, ENSIETA, Ecole Navale, AMURE and ISEN. Thales is responsible for the overall project coordination, the high resolution sonar sensor and associated on-board intelligence processing, as well as the system deployment. ECA ROBOTICS is in charge of the design of the autonomous underwater vehicle itself and all aspects linked directly to the navigation, autonomous behavior and communications. This innovative AUV (Autnomous Underwater Vehicle) will feature high levels of decision-making autonomy, generation of high-resolution underwater imagery from depth and compatibility with standard off-the-shelf equipment. The system will also have the capability to track changes in the undersea environment between subsequent missions and compare the objects it detects with those stored in its database. Sea trials have been conducted from beginning of 2010 until end of April 2010, at first in the South of France, near Toulon, to validate the behavior of the vehicle and its components in various conditions, and then in the West of France, near Brest, to validate the sonar performance when integrated in the vehicle and the global system performances. During these sea trials, the AUV has demonstrated its capacity to perform large missions in full autonomy. The advanced technologies developed in this ASEMAR project have allowed to perform at sea the demonstration of an autonomous underwater vehicle able to perform surveillance missions over large areas, with a high level of performance thanks to its high level of autonomy.

 
Technical Data
Back to top
Design
The main components of the ASEMAR AUV are the embedded intelligence, the sonar payload, the navigation function and the vehicle.
Mobilty
The ASEMAR has a cylindrical aluminum shape, a single propeller for an optimized autonomy. The energy is provided by a lithium-Ion embedded battery.
Accessories
The main components of the ASEMAR are the embedded intelligence, the sonar payload, the navigation function and the vehicle. The ASEMAR may communicate with the surface ship through an acoustic link; sonar and navigation data are recorded on board the AUV. To secure its main capabilities, the ASEMAR AUV takes benefit of efficient functions and sub-systems. THALES has developed a challenging on board processing that will perform automatic target recognition and determine adaptive behaviour as part of the mission management.
Mission
The mission of the ASEMAR is the detection of the immersed dangers. Its spectrum of use is very wide: from the search of sunk ships or cargoes of hazardous or polluting materials lost offshore, to the observation of seismic faults or geologic movements. The ASEMAR has the ability to operate in an unknown area and can detect, classify and localize suspicious objects laying on the sea-bed. To perform its missions, the ASEMAR is equipped with high resolution sonar linked to one operation centre container for mission supervision and data processing. One container is used for the transportation, storage and maintenance.
