Stable Working Condition for Survey


- Excellent stability, roll range smaller than 10 degrees in SS4.


- Catamaran design significantly reduces swaying and spray foam, providing stable and quiet working condition for acoustic equipment


- Low noise electric Plug-in thruster, reduces signal-to-noise ratio by 20%



Autonomous Control with High Precision


- Radar, HD camera and AIS sensing enabling highly sensitive environmental perception


- Dual engine and dual propeller providing large torque, L25 can rotate in situ


- Able to navigate closely around constructions for zoom-in inspection


- Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm applied to minimize risk of collision

The L25 USV can carry up to 200kg of hydrographic & geophysical instruments to conduct multi-purposed physical oceanographic surveys and biological environment monitoring on the deep sea.

Large Capacity for Multi-function Instruments

 

Wider deck, bigger payload, supporting multiple equipment work simultaneously for underwater inspection, hydrography survey and oceanography survey

Hydrographic Survey USV

Auto Return

 

During a mission, if the L25 loses communication or is about to run out of power, it can automatically sail back to the designated location to avoid getting lost on the sea

Advanced Design for Easy Configuration

Small A-frame and winch support towing survey, cable length up to 200 meters;

Foldable lifter protects instruments wet ends and offers greater payload capacity.
