CHCNAV Apache 3 Pro USV — Precision Hydrographic Surveying in Any Waterway
The CHCNAV Apache 3 Pro is a professional-grade unmanned surface vessel (USV) built for accurate bathymetric and hydrographic surveying in shallow waters, rivers, coastal zones, and urban waterways. With a rugged trimaran hull, integrated GNSS/IMU navigation, and anti-collision LiDAR, it delivers centimeter-level results without putting a crew on the water.
Imagine one person unloading the Apache 3 Pro from a truck, deploying it in minutes, and collecting high-resolution bathymetric data across a fast-moving river channel — autonomously, from the shore. That’s what this platform is built for.
