The CHCNAV APACHE 4 Autonomous Hydrographic & Bathymetric Survey USV is a compact professional unmanned surface vessel designed for hydrological studies, hydrographic surveying, bathymetric mapping, water-flow measurement, and ADCP survey applications. Its shallow draft, stable navigation, and flexible instrument integration make it particularly well suited for rivers, lakes, reservoirs, shallow waterways, and challenging survey environments.

Designed around professional hydrological workflows, the APACHE 4 supports a variety of Acoustic Doppler Current Profilers (ADCPs) and compact multibeam systems. Its central access shaft accommodates instruments including the CHCNAV RS Series, M9, RTDP 1200, RiverPro, and RiverRay, as well as the CHCNAV HQ compact multibeam echosounder, side-scan sonar, and water-quality probes.

Integrated GNSS + IMU technology provides accurate positioning, heading, and attitude information while supporting autonomous navigation. The system is designed to maintain useful positioning and attitude information during temporary GNSS interruptions, such as when operating beneath bridges. An advanced navigation controller with adaptive water-flow technology helps the APACHE 4 accurately follow hydrographic cross-sections and maintain a stable position at observation points.

The APACHE 4 also incorporates a 200 kHz single-beam echosounder with a measurement range from 0.1 to 200 meters. This allows operators to collect depth profiles alongside flow-velocity measurements and provides an additional means of verifying ADCP bottom-tracking data.

Key Features

Efficient Hydrographic Surveying

The APACHE 4 supports professional water-flow and velocity measurements using stable GNSS positioning and automated navigation. It is particularly suited for ADCP hydrographic cross-section measurements, allowing hydrologists to collect flow data efficiently across rivers and waterways.

Integrated GNSS + IMU Positioning

Full GNSS + IMU integration provides accurate positioning, heading, and attitude information for autonomous navigation and survey data collection.

Combining GNSS and inertial measurements also helps compensate for vessel motion and improves the quality of positioning information during challenging survey conditions.

Accurate Operation Under Bridges

Bridge crossings and similar obstructions can temporarily interrupt GNSS reception. The integrated GNSS and IMU sensors help provide position and attitude information during these interruptions while compensating for hull sway and helping reduce data outliers.

This capability is particularly valuable during river cross-section surveys where bridges may be located directly within the survey area.

Versatile ADCP Compatibility

The APACHE 4's central access shaft supports a variety of professional ADCP systems, including:

• CHCNAV RS Series
• M9
• RTDP 1200
• RiverPro
• RiverRay

This allows survey teams to integrate the APACHE 4 into different water-flow and discharge measurement workflows.

Support for Multiple Survey Sensors

Beyond ADCP applications, the APACHE 4 can accommodate additional hydrographic and environmental equipment, including:

• CHCNAV HQ Compact Multibeam Echosounder
• Side-Scan Sonar
• Water Quality Probes

This flexibility allows the APACHE 4 to serve as a multifunctional survey platform rather than being limited to a single measurement application.

Integrated 200 kHz Single-Beam Echosounder

The built-in 200 kHz single-beam echosounder provides depth measurements from 0.1 to 200 meters.

When performing ADCP surveys, the integrated echosounder can provide water-depth profiles alongside flow-velocity measurements and assist with verification of ADCP bottom-tracking information.

Advanced Navigation Controller

The APACHE 4 uses an advanced navigation controller with adaptive water-flow technology to help the vessel accurately navigate hydrographic cross-sections.

Stable Hovering

The vessel's hovering capability helps maintain its position at observation points, improving flow estimation where stable measurements are important. This is especially useful in turbulent or moving water.

Shallow 8.6 cm Draft

With an unloaded draft of only 8.6 cm, the APACHE 4 is well suited for surveys in shallow rivers, lakes, reservoirs, and waterways where conventional survey boats may be difficult to deploy.

Up to 40 kg Payload Capacity

The APACHE 4 supports payloads of up to 40 kg, allowing operators to integrate different hydrographic, hydrological, and environmental sensors depending on project requirements.

Maximum Speed Up to 6.5 m/s

With a maximum specified speed of 6.5 m/s, the APACHE 4 combines survey capability with efficient movement between survey locations.

360° Video Camera

An integrated 360-degree video camera gives operators visual awareness around the vessel during remote and autonomous survey operations.
