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. Key Features Trimaran Hull for Superior Stability — Tracks straight and stable even in current-heavy or narrow river channels Multi-Echo Sounder Compatible — Supports MBES, SBES, ADCP, SVS, and GNSS/INS payloads Integrated GNSS + IMU Navigation — Precise motion compensation for high-quality bathymetric data with or without RTK base stations Optional ADCP Integration — Real-time water flow speed and discharge measurement Anti-Collision LiDAR + HD Camera — Autonomous obstacle detection and route planning for hands-free missions Remote & Autonomous Control — Full mission planning, execution, and real-time monitoring from shore Lightweight & Modular — Single-person deployment with easy transport and fast battery swaps in the field Technical Specifications Hull Design: Trimaran Dimensions: 1.6 × 0.8 × 0.5 m Weight: ~30 kg (excluding payload) Payload Capacity: Up to 15 kg Propulsion: Dual thrusters Max Speed: 4.5 m/s Battery Endurance: Up to 6 hours (mission and payload dependent) Control Range: Up to 5 km (with stable LOS signal) Navigation: GNSS + IMU + LiDAR obstacle avoidance Compatible Sensors: MBES, SBES, ADCP, SVS, GNSS/INS Ideal Use Cases River and lake bathymetry Sediment and flow monitoring Coastal and reservoir surveying Flood risk assessment Port and harbor maintenance Civil engineering water studies CHCNAV’s Apache 3 Pro combines trimaran stability, multi-sensor compatibility, and autonomous navigation in a compact, field-ready platform — the professional’s choice for waterborne survey missions that demand precision and efficiency.
