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.
