French acoustics specialist RTSYS has launched its latest versatile micro autonomous underwater vehicle (AUV) NemoSens, designed to perform numerous civil applications such as seabed imagery, environmental monitoring or wreckage localization.
Unveiled after years of development, the flexible new AUV is small (less than 1 meter long) and is easy to carry and launch (less than 20 pounds including payload). Micro-AUV NemoSens can host any kind of payload, be it a CTD probe, sidescan sonar or any other sensors. Thanks to an open LINUX architecture it can be programmed from a ROS or MOOS interface to complete various kind of missions.
Its battery provides wide autonomy (up to 8 hours at 4 knots) with speed range from 2 to 8 knots and its robustness allows it to dive over 300 meters, the manufacturer said,
Several AUVs can maneuver in swarm (+10) thanks to acoustics; beacons on the surface could also be used for real-time repositioning. Navigation is accurate thanks to integrated INS along with a GPS and a flasher in the mast for smooth recovery.
