The CHCNAV APACHE 4 Pro Multi-Purpose Hydrographic & Bathymetric Survey USV is a versatile unmanned surface vessel designed for professional hydrographic, bathymetric, hydrological, and environmental survey applications. Built around a high-strength carbon-fiber platform, the APACHE 4 Pro combines autonomous navigation, precise GNSS and IMU positioning, obstacle avoidance, and flexible payload integration in a compact survey vessel.

Designed for operation in rivers, lakes, reservoirs, inland waterways, and coastal environments, the APACHE 4 Pro can support a wide variety of survey instruments. Its central access shaft accommodates compatible ADCPs, multibeam echosounders, side-scan sonar, water-quality probes, and other hydrographic sensors, allowing the vessel to be configured for different projects rather than being limited to a single survey application.

The APACHE 4 Pro combines multi-constellation GNSS positioning with an integrated IMU to maintain accurate position and attitude information. This becomes particularly important when surveying near or beneath bridges, where temporary GNSS interruptions can occur. The navigation system compensates for vessel motion and helps maintain reliable survey data during challenging field conditions.

Two configurations are available. The 8004 010 058 package is equipped with a D270 single-beam echosounder, while the APACHE 4 Pro-HN-400M configuration incorporates an HN-400M multibeam echosounder for more comprehensive underwater mapping and bathymetric data acquisition.

Which Package Should I Choose?

8004 010 058 – APACHE 4 Pro with D270 Single-Beam Echosounder

Choose the APACHE 4 Pro with D270 when your primary requirement is depth profiling, hydrographic cross-sections, or integration with flow-measurement workflows.

The single-beam configuration is particularly useful when combining depth measurements with compatible ADCP data. The echosounder can provide a water-depth profile alongside flow-velocity measurements and can be used to verify ADCP bottom-tracking information.

Recommended For:

• Single-Beam Bathymetry
• River Cross-Section Surveys
• ADCP Surveys
• Flow & Velocity Measurements
• Hydrological Surveys
• Lake & Reservoir Depth Surveys
• Environmental Monitoring
• Inland Waterway Surveys

APACHE 4 Pro-HN-400M – with HN-400M Multibeam Echosounder

Choose the HN-400M multibeam configuration when your project requires more detailed underwater mapping and broader bathymetric coverage than a single-beam system provides.

This configuration is better suited for projects where collecting detailed bottom-surface information across a wider survey area is important.

Recommended For:

• Multibeam Bathymetric Surveys
• Detailed Underwater Mapping
• Riverbed Mapping
• Lake & Reservoir Mapping
• Coastal Hydrographic Surveys
• Infrastructure Surveys
• Detailed Bottom-Surface Surveys
• Professional Hydrographic Mapping

Key Features

Multi-Purpose Hydrographic USV

The APACHE 4 Pro is designed as a flexible unmanned surface vessel platform rather than a single-purpose survey boat.

Its modular configuration allows survey professionals to adapt the vessel for bathymetry, flow measurement, environmental monitoring, and other hydrographic applications.

Multi-Constellation GNSS + IMU

The integrated positioning system combines multi-constellation GNSS with an IMU to provide accurate position and vessel-attitude information.

The IMU helps compensate for vessel movement and supports data continuity when operating in environments where GNSS conditions may temporarily become less reliable.

Improved Performance Around Bridges

Bridge structures can obstruct satellite signals and create challenging conditions for hydrographic surveys.

The APACHE 4 Pro's integrated GNSS and IMU solution helps maintain position and attitude information during temporary GNSS outages while compensating for hull movement and helping reduce data outliers.

Advanced Autonomous Navigation

The APACHE 4 Pro incorporates an advanced navigation controller designed to accurately follow planned survey lines and cross-sections.

Adaptive water-flow technology helps the vessel maintain its intended survey path when working in moving water.

Hovering Capability

The vessel's hovering functionality helps maintain stability at observation points, even in turbulent conditions.

This capability is particularly useful during flow and velocity measurement applications where maintaining a stable observation position can improve measurement consistency.

Up to 6.5 m/s Maximum Speed

The APACHE 4 Pro has a specified maximum speed of up to 6.5 m/s, providing the mobility needed to efficiently navigate survey areas.

50 kg Payload Capacity

With a payload capacity of up to 50 kg, the platform can support a variety of hydrographic and environmental instrumentation.

Central Access Shaft

The APACHE 4 Pro's central access shaft allows compatible survey instruments to be integrated directly into the vessel.

Supported equipment can include ADCPs, multibeam echosounders, side-scan sonar, and water-quality probes.

ADCP Compatibility

The APACHE 4 Pro supports compatible ADCP systems including:

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

This makes the platform well suited for hydrographic cross-section and water-flow measurement applications.

Single-Beam Bathymetry

The D270 configuration provides single-beam depth measurement for hydrographic and bathymetric surveys.

The supplied single-beam specifications provide a measurement range from 0.1 to 200 meters with specified accuracy of ±0.01 m + 0.1% × D.

Multibeam Configuration Available

For projects requiring more detailed underwater coverage, the APACHE 4 Pro can be configured with the HN-400M multibeam echosounder.

This configuration expands the platform from single depth profiling to more comprehensive multibeam bathymetric mapping.

360-Degree Video

An integrated 360° video camera provides visual awareness around the USV during survey operations.

Obstacle Avoidance

The APACHE 4 Pro includes obstacle-avoidance capability to support safer autonomous navigation during field operations.

Additional Payload Compatibility

The platform can also support additional hydrographic and environmental equipment, including:

• Multibeam Echosounders
• ADCPs
• Side-Scan Sonar
• Water-Quality Probes
• ASVPK Automatic Sound Velocity Profiler Kit

Specific equipment requirements and compatibility should be confirmed when configuring the system.
