USV with Integrated ADCP and Echo sounder
ADVANCED NAVIGATION CONTROLLER
APACHE 4 hover stably in the turbulent flow at the start and end points of ADCP observation, thereby improving the accuracy of flow estimation.
COMPATIBLE WITH ADCP
Carries up to 30 kg of payload. It does not only carry the ADCP, but also provides its positioning, orientation, power, waterproofing, network and 4G transmission.
BUILT-IN SINGLE BEAM
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.
