Fast Switch Between Missions

Instruments, like ADCPs, echo sounders and side scan sonars, with a diameter of 5 cm to 18 cm, can be installed rapidly into the central moonpool, allowing you to switch between missions with ease.

Multibeam Echo Sounder Solution

In addition to the above instruments, SL40 can also be upgraded to a multi-beam echo sounder solution which has been proven to be highly mature and stable after repeated tests.

The optional MBES model includes R2sonic 2020 and Hydro-Tech YH400P.

Automatic mission planning

You can pre-program the survey mission with just a few drags and clicks on the base station computer. SL40 carrying instruments can conduct surveys autonomously and send back real-time data.

You can also drive SL40 by a remote controller to reach some difficult corners.

SL40 collision avoidance 14 e1553848000275

Intelligent collision avoidance

Equipped with radar sensors, SL40 USV can detect obstacles and avoid collision within 50 meters.

In manual mode, you can observe the water environment via real-time video to improve navigation safety.
