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
