APACHE 4
AUTONOMOUS HYDROGRAPHIC

MARINE SURVEY
& CONSTRUCTION
CHCNAV · APACHE 4
ADVANCED NAVIGATION
CONTROLLER
The autonomous control system enables
APACHE 4 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.
Integrated adaptive water flow straight
-line and hovering technology.
BUILT-IN SINGLE-BEAM
ECHO SOUNDER
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.
Expand your unmanned survey capability.
SMART POSITIONING
AND NAVIGATION
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.
Interrupted positioning with GNSS+IMU.
COMPATIBLE WITH MOST
COMMON ADCPS
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.
Versatile. Carries up to 30 kg of payload.
AUTONOMOUS
SURVEY USV
HYDROGRAPHIC
The APACHE 4 is an Unmanned Surface Vessel (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. Very compact, it enables easy handling at the mission
site, facilitates safe launching and convenient transportation by car.
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.
The APACHE 4 is a perfect solution for obtaining high quality data for flow and velocity measurements
in water where manned boat access is impractical, such as in front of dam structures, or where safety
is a concern, such as during flood level measurements.
