SL40 | Unmanned Surface Vehicle丨OceanAlpha

Rapid installation with ADCP and echosounder

Instruments, like ADCPs, ecosounders and side scan sonars, with diameter of 5 cm to 18 cm can be rapidly installed to the dedicated cabin on the USV.

User can pre-program the survey mission with the base station on the bank. The USV and instruments can conduct surveys autonomously and send back real-time data.
User can also drive the USV manually by a remote controller.

With ultrasonic sensors, SL40 USV can detect and bypass obstacles 10 meters ahead to avoid collision.
In manual mode, user can observe water environment by the real-time video feed to better avoid obstacles.

The innovative waterjet propeller allows SL40 USV to sail at 5m/s and effectively avoid being entangled by water plants or rubbishes.

The trimaran hull design highly improve the sailing stability in high speed.
