CHCNAV APACHE 3 PRO

The CHCNAV Apache 3 Pro is a compact unmanned surface vehicle (USV) designed for autonomous bathymetric surveys in shallow water environments such as rivers, lakes, and reservoirs. Built with a lightweight carbon-fiber hull and equipped with GNSS RTK and inertial navigation, it delivers highly accurate positioning and depth measurements while operating safely and efficiently in challenging conditions. Its integrated single-beam echosounder and smart navigation system allow surveyors to collect precise hydrographic data with minimal crew and setup.

High-precision positioning: GNSS RTK combined with INS maintains accurate positioning even when satellite signals are temporarily blocked.
Integrated echosounder: Built-in single-beam sonar provides reliable depth measurements for bathymetric mapping and reservoir volume calculations.
Autonomous and efficient: Lightweight design, intelligent power management, and dual communication (4G and remote control) enable easy one-person operation and reliable survey missions.

Integrated data acquisition, post-processing, and real-time parameter display.

Benefits and Performances

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.

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.
