Unmanned Surface Vessels

Definition

Unmanned Surface Vessels (USVs) are autonomous or remotely operated boats that can navigate and perform tasks on water without a human crew onboard. These vessels have gained importance in various applications, including bathymetric surveying, where they can gather data about the underwater topography and other environmental factors efficiently and safely. USVs can operate in challenging conditions and access areas that may be hazardous for manned vessels, making them a valuable tool for data collection and analysis.
