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. |
|
Advanced Design for Easy Configuration
· Small A-frame and winch support towing survey, cable length up to 200 meters; · Foldable lifter protects instrument’s wet ends and offers greater payload capacity |
|
Stable Working Conditions 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 conditions 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 minimise the risk of collision |
|
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. |
