USV
Apache 4 CHCNAV
The APACHE 4 USV is optimized for hydrological studies, supporting a range of ADCP and compact multi-beam systems. Its shallow draft, high accuracy, and stable hovering make it ideal for measuring water flow velocity and discharge.
ADVANCED NAVIGATION CONTROLLER
Navigate accurately along cross-sections with adaptive water flow technology. The hovering feature improves flow estimation accuracy by maintaining stability at observation points, even in turbulent conditions.
INTEGRATED SINGLE-BEAM ECHOSOUNDER
Verify ADCP bottom-tracking data using the built-in single-beam echosounder. It provides water depth profiles in conjunction with flow velocity measurements, significantly extending the ADCP's sounding range.
