CHCNAV APACHE 3 PRO
High Performance, Cost-Effective Single Beam USV
Cost-Effective Autonomous USV
The APACHE 3 Pro is an autonomous USV engineered for high-performance bathymetry in shallow environments. It combines a robust carbon fiber design with a fully integrated single-beam echosounder.
What sets the APACHE 3 Pro apart is its navigation stability. By utilizing GNSS RTK paired with Inertial Navigation Systems (INS), the vessel maintains precise positioning and data integrity, even when satellite signals are obstructed by bridges or complex infrastructure.
Key Features
Lightweight
Only 10kg and just over 1m in length for easy transportation and operation
GNSS+INS Positioning
Precise positioning and heading, ensuring an accurate survey
CHCNAV D270 Echosounder
Providing accurate depth measurements
Android-based EasySail
Ensuring ease of usability, and support for our custom AnyDesk instance for getting you out of those tricky "it's this button!" moments
Features
The APACHE 3 Pro USV features a one-piece moulded carbon fibre hull ensuring both strength and impact resistance. The weight and design allows for easy single-person transport and deployment.
With the CHCNAV D270 single-beam echosounder, you can ensure delivery of reliable and accurate depth measurements. Its integrated water temperature sensor corrects sound velocity in realtime for enhanced depth measurement performance.
Minimise 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.
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.
The APACHE 3 Pro’s remote controller comes pre-installed with the Android-based EasySail software, removing the need for external computers. The software includes real-time video transmission, parameter monitoring, and an integrated suite for path planning, data logging, and processing.
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.
