CHCNAV Apache 4 Pro USV — Autonomous Hydrographic Survey Vessel for Professional Waterborne Mapping
The CHCNAV Apache 4 Pro USV is a professional-grade unmanned surface vessel engineered for high-precision hydrographic and bathymetric survey operations. Built on a rugged catamaran platform, it integrates multi-beam echo sounder (MBES) compatibility, centimeter-level RTK/GNSS/IMU positioning, and anti-collision LiDAR into a compact, one-person deployable system. Jet pump propulsion eliminates debris risk in shallow or cluttered waterways, while autonomous route planning enables hands-free mission execution across rivers, reservoirs, coastal zones, and beyond.
