CHCNAV APACHE 3 PRO Unmanned Survey Boat

Overview

The CHCNAV APACHE 3 PRO is a professional unmanned surface vehicle (USV) designed for single beam bathymetric surveying in rivers, lakes, reservoirs, and shallow waterways. It combines a 200 kHz echo sounder, GNSS RTK positioning, inertial navigation, and autonomous vessel control to collect accurate water depth data without requiring survey personnel onboard.

Equipped with intelligent obstacle avoidance, a 360° camera, and EasySail surveying software, the APACHE 3 PRO provides a practical solution for hydrographic survey teams conducting underwater terrain mapping, reservoir capacity investigations, and waterway maintenance surveys.

Key Features

Integrated D270 Single Beam Echo Sounder

The APACHE 3 PRO features a 200 kHz single beam echo sounder with a specified sounding range of 0.1–200 m. The system collects depth measurements together with GNSS positioning data for bathymetric mapping.

GNSS RTK and Inertial Navigation

Integrated dual-antenna GNSS and IMU technology support accurate positioning, heading determination, and stable survey navigation. The specified RTK accuracy is ±8 mm + 1 ppm horizontally and ±15 mm + 1 ppm vertically.

Autonomous Survey Missions

EasySail software supports survey route planning, automatic navigation, vessel control, and real-time display of sounding information. Operators can monitor survey progress and manage data collection remotely.

Millimeter-Wave Obstacle Avoidance

The vessel uses millimeter-wave radar to detect obstacles along its route, helping reduce collision risks during autonomous surveying.

360° Visual Monitoring

An onboard camera provides panoramic video monitoring, allowing operators to observe the vessel's surroundings while working from shore.

Extended Battery Operation

The APACHE 3 PRO supports up to 10 hours of operation at 1.5 m/s under specified battery conditions. Hot-swappable battery support helps reduce interruptions during longer field surveys.

Flexible Communication

2.4 GHz remote control and 4G connectivity provide options for vessel operation and monitoring according to communication coverage and field requirements.

Triple-Hull Design

Its carbon fiber triple-hull structure, 10 cm draft, and IP67 protection support deployment in inland waterways and other hydrographic survey environments.
