BUILT-IN SINGLE BEAM

ECHO SOUNDER

Single beam sounding data can be used to verify the accuracy of ADCP bottom tracking data. Provide water depth profile data associated with the flow velocity profile measurement.

SMART POSITIONING AND NAVIGATION

APACHE 4 stable position and heading to the ADCP and autopilot. Its IMU sensor ensures the availability of position data even during GNSS signal loss.

Completely autonomous.
