The APACHE 4 is an Unmanned Surface Vehicle (USV) that supports a wide variety of Acoustic Doppler Current Profiler (ADCP) systems available on the market. It offers an unmanned operation solution with a shallow draft, high navigational accuracy and stable hovering for hydrologists when measuring water flow velocity and discharge of a current section.

Designed for the efficient hydrographic, bathymetric, and hydrological surveys, the APACHE 4 USV brings together the best of high-accuracy positioning and automated navigation control technology, built around the operator's habits when conducting ADCP hydrographic cross-section flow measurements.The built-in adaptive water flow and hovering navigation technology significantly improves the accuracy of flow estimation. Even when GNSS positioning might be degraded by obstructed environments, the internal GNSS+IMU module continues to provide reliable position and heading for the ADCP and autopilot controller.
