Autonomous hydrographic and bathymetric survey USV
Adaptive water flow straight-line and hovering technology
The APACHE 4 control system enables to navigate straight along the cross-section according to the profile view when the flow rate, turbulence, etc. change. The hovering technology can make APACHE 4 hover stably in the turbulent flow at the start and end points of ADCP observation, thereby improving the accuracy of flow estimation
Versatile. Carries up to 30 kg of payload
The APACHE 4 central access shaft design provides unmanned cross-sectional flow measurement solutions for the leading ADCPs on the market. The APACHE 4 is particularly suited for hydrologists using ADCP sensors such as the M9, RTDP 1200, RiverPro and RiverRay who are looking for an integrated, portable, and affordable unmanned solution. It does not only carry the ADCP, but also provides its positioning, orientation, power, waterproofing, network and 4G transmission solutions
Expand your unmanned survey capability
Single beam sounding data can be used to verify the accuracy of ADCP bottom tracking data, and even fed directly into the ADCP flow measurement software to compensate for the unavailability of ADCP data, and at the same time provide water depth profile data associated with the flow velocity profile measurement
Uninterrupted positioning with GNSS+IMU
APACHE 4 provides stable position and heading to the ADCP and autopilot. Its IMU sensor ensures the availability of position data even during momentary GNSS signal loss. The obstacle avoidance radar system and live video feed ensure safe operations in case of loss of visibility or difficult environmental conditions. Completely autonomous, the APACHE 4 is safely operated from the shore. The AutoPlanner and HydroSurvey software suite allows the operator to define the entire mission, from the survey area to the export of the results
