CHCNAV APACHE 3 PRO

High Performance Single Beam USV

The APACHE 3 Pro is a compact unmanned surface vehicle (USV) designed for autonomous bathymetric surveys in shallow water environments, including lakes, rivers, and coastal areas. Its lightweight carbon fibre hull makes it easy to deploy, while advanced GNSS RTK + INS navigation delivers reliable positioning in the field.

With an integrated single-beam echosounder, the APACHE 3 Pro provides accurate depth measurements, maintaining stability and performance even in challenging conditions such as under bridges or around infrastructure—making it well suited to a variety of Australian hydrographic survey applications.

Features

GNSS RTK + INS

Precise positioning even when GNSS signal are lost.

Intelligent Power Management

Balanced power supply for uninterrupted missions.

CHCNAV D270 Echosounder

Accurate depth measurements.

Android-based EasySail

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

Benefits

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.

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.

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.

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.

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.

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.
