USV-6S​   Unmanned Surface Vehicle (USV)

Compact Surveying & Monitoring Platform

Equipped with Tri‑Frequency Side‑Scan Sonar

The USV‑6S is a highly integrated, lightweight Unmanned Surface Vehicle (USV).

Engineered for rapid deployment in bathymetric surveying, environmental monitoring, and emergency response, the USV‑6S combines advanced sensors, artificial intelligence, and reliable communication technologies in a professional platform to ensure high efficiency and accuracy for work. With a length of 0.98 meters and a featured M‑shaped hull, it ensures stable and safe navigation in various water areas.

Despite its compact size, it does not compromise on capability. The system comes standard with a high‑precision GNSS module and a single‑beam echosounder, with optional water quality sensors available for flexible mission configuration. It is the ideal, cost‑effective, and one‑stop solution.

USV-6S Unmanned Surface Vehicle
