CHCNAV Apache 4 Autonomous Hydrographic & Bathymetric Survey USV w/ Software - 8004010042

The APACHE 4 USV is optimized for hydrological studies, supporting a range of ADCP and compact multi-beam systems. Its shallow draft, high accuracy, and stable hovering make it ideal for measuring water flow velocity and discharge. Compact and easy to handle, it ensures effortless site management, safe launches, and convenient car transport. With integrated GNSS+IMU technology, it provides reliable positioning and heading, enhancing ADCP and autopilot functionality for precise water flow analysis.

• Efficient Hydrographic Surveying: Perform high-quality flow and velocity measurements with stable GNSS positioning and automated navigation. Ideal for hydrologists conducting ADCP hydrographic cross-section flow measurements.
• Accurate Even Under Bridges: Maintain high accuracy under bridges with integrated GNSS and IMU sensors. The APACHE 4 provides precise position and attitude data, compensating for hull sway and eliminating data outliers during GNSS outages.
• Versatile Instrumentation Compatibility: With its central access shaft design, the APACHE 4 supports ADCPs such as the CHCNAV RS Series, M9, RTDP 1200, RiverPro and RiverRay. It also accommodates the CHCNAV HQ compact multibeam echosounder, side-scan sonar and water quality probes for end-to-end surveys.
• Integrated Single-Beam Echosounder: Verify ADCP bottom-tracking data using the built-in single-beam echosounder. It provides water depth profiles in conjunction with flow velocity measurements, significantly extending the ADCP's sounding range.
• Advanced Navigation Controller: Navigate accurately along cross-sections with adaptive water flow technology. The hovering feature improves flow estimation accuracy by maintaining stability at observation points, even in turbulent conditions
