CHCNAV Apache4 USV | Autonomous Hydrographic and Bathymetric Surveys USV

The CHCNAV APACHE4 USV is an advanced unmanned surface vessel (USV) designed for precise hydrographic surveys and flow measurements in challenging water environments. Its compact and robust design allows for easy deployment, while its advanced navigation technology ensures stability and accuracy even in turbulent conditions. The APACHE4 is ideal for hydrologists conducting Acoustic Doppler Current Profiler (ADCP) surveys, offering enhanced data reliability and safety in environments where traditional manned surveys may not be feasible.

Key Features:

Advanced Navigation Controller:

• Ensures straight-line navigation and stable hovering, even in turbulent flows, improving flow estimation accuracy.

Integrated Single-Beam Echo Sounder:

• Verifies ADCP bottom tracking data and provides water depth profile data, ensuring comprehensive survey results.

Smart Positioning and Navigation:

• Combines GNSS and IMU to maintain positioning accuracy, with millimeter-wave radar and live video feed for safe operations in difficult environments.

ADCP Compatibility:

• It supports a wide range of ADCPs and offers a versatile solution for hydrologists.

Energy-Efficient Motor:

• The brushless DC motor provides high performance and durability, with a top speed of 6 m/s.

Autonomous Operation:

• Supports manual and autopilot modes with features like auto-return and obstacle avoidance for enhanced safety.

The APACHE 4 USV is a state-of-the-art solution for conducting hydrographic surveys and ADCP measurements in environments where manned vessels may not be safe or practical. Its robust design, combined with advanced navigation and positioning technology, ensures reliable and accurate data collection. The APACHE 4 is especially suited for use in areas with challenging water conditions, such as in front of dam structures or during flood level measurements.
