OceanAlpha USV SL40 USV

Unique waterjet hydrographic surveying USV platform

SL40 autonomous survey boat is a waterjet-propelled unmanned surface vessel (USV) for hydrographic and bathymetric survey. Measuring 1.6 meters long and 0.7 meters wide, SL40 weighs 35 kg and can carry 15 kg of survey instrumentation. The innovative waterjet propeller allows the USV to sail at 5m/s and effectively avoid being entangled in water plants or rubbish. The USV comes with obstacle avoidance system and RTK, and can be controlled by either a base station or a remote control.

Description

Product Highlight:

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.

Automatic mission planning

  • 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.

Intelligent collision avoidance

  • 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.

Higher speed & tangling free

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

Stable sailing

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