Oceanographic survey USV L25

for hydrographic surveysfor underwater topographic mappingfor underwater object detection

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. ① Large Capacity for Multi-function Instruments · Wider deck, bigger payload, supporting multiple equipment work simultaneously for underwater inspection, hydrography survey and oceanography survey. ② Longer Endurance, High Efficiency · The internal combustion engine can extend the battery life to 72 hours. · Long endurance enables round-clock inspection, feedbacking real-time data & video. ③ 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. ④ 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% ⑤ 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 · Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm applied to minimize risk of collision ⑥ 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.
