The APACHE 3 Pro, USV, Autonomous Bathymetric Survey Boat

The CHCNAV APACHE 3 Pro is a compact unmanned surface vehicle (USV) for autonomous bathymetric surveys in shallow water environments such as lakes, rivers, and coastal zones. Its lightweight carbon fiber hull, advanced GNSS RTK + INS navigation, and integrated single-beam echosounder ensure precise depth measurements and stable positioning, even in challenging conditions such as under bridges or near infrastructure.

Dual-Mode Communication

Maintain stable data and control links through 4G connectivity and 2.4 GHz remote communication. Easily switch between SIM and manual control modes for seamless operations in diverse environments.

Adaptable Performance

Engineered with high-sensitivity, anti-interference transducers and adaptive bathymetric algorithms, the Apache 3 Pro adjusts automatically to variable water terrains, delivering high-resolution data in complex survey scenarios.

Anti-Entanglement Design

Minimize downtime with a titanium alloy mesh guard and hybrid water pressure conversion system that reduce the risk of aquatic vegetation entanglement. The system alerts operators if an obstruction is detected, protecting the motor during critical missions.

High-Precision Navigation

Maintain consistent survey accuracy even in GNSS-denied environments. The integrated GNSS RTK and Inertial Navigation System ensures precise positioning under bridges, along urban waterways, and in other signal-obstructed areas.

Advanced Depth Measurement

Deliver reliable and accurate bathymetric data using the CHCNAV D270 single-beam echosounder. Its integrated water temperature sensor corrects sound velocity in real time for enhanced depth measurement performance.

Smart Power Management

Stay mission-ready with an intelligent power system that supports hot-swappable batteries. In case of interruption, the Apache 3 Pro resumes its route from the exact point of disruption, ensuring operational continuity.
