CHCNAV Apache 4 GNSS Survey Boat
Recommended List Price£32,000.00
The APACHE 4 Unmanned Surface Vessel (USV) is designed for hydrological surveys, accommodating various Acoustic Doppler Current Profilers (ADCPs) and compact multibeam echosounders. Its shallow draft, precise measurements, and stable hovering capabilities make it perfect for determining water flow velocity and discharge. The compact design allows for easy handling, safe deployment, and convenient transport by car, simplifying fieldwork. Integrated GNSS and Inertial Measurement Unit (IMU) technology provide dependable positioning and heading data, improving the performance of both the ADCP and autopilot systems for accurate water flow analysis.

Benefits and performance
- Efficient Hydrographic Surveys: Conduct precise flow and velocity measurements with stable GNSS positioning and automated navigation. The Apache 4 is an ideal solution for hydrologists performing ADCP-based hydrographic cross-section flow assessments.
- Uninterrupted Accuracy, Even Under Bridges: Maintain high accuracy, even beneath bridges, thanks to integrated GNSS and IMU sensors. The Apache 4 delivers precise position and attitude data, compensating for hull motion and mitigating data errors during GNSS signal loss.
- Flexible Instrument Integration: The Apache 4’s central access shaft design allows for compatibility with a range of ADCPs, including the CHCNAV RS Series, M9, RTDP 1200, RiverPro, and RiverRay. It also supports the CHCNAV HQ compact multibeam echosounder, side-scan sonar, and water quality probes for comprehensive surveys.
- Integrated Single-Beam Echosounder for Enhanced Data: Corroborate ADCP bottom-tracking data with the integrated single-beam echosounder. This feature provides water depth profiles alongside flow velocity measurements, significantly extending the ADCP’s effective sounding range.
- Intelligent Navigation and Control: Navigate cross-sections accurately with adaptive water flow technology. The hovering capability enhances flow estimation precision by maintaining stability at measurement points, even in challenging, turbulent environments.
Use Cases
- Flood Risk Assessment
- Sediment Transport Studies
- Port Current Analysis
- River Discharge Measurement
