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 the ultrasonic sensors, the 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 the 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.
