Compact Hydrographic Drone
CHCNAV Apache 3 Pro USV for Shallow-Water Bathymetric Surveys
The CHCNAV Apache 3 Pro is a compact single-beam hydrographic USV designed for bathymetric surveys in shallow water, including rivers, channels, ponds, reservoirs, inland waterways, and near-shore environments.
Built as a highly integrated platform, it combines GNSS RTK + INS navigation, a CHCNAV D270 single-beam echosounder, obstacle avoidance radar, 360° video, onboard storage, and 4G / 2.4G communications in one portable survey system.
With its lightweight design, rugged hull, shallow draft, semi-embedded motor system, and autonomous survey capability, the Apache 3 Pro helps survey teams work more safely, move faster in the field, and complete hydrographic projects with less manpower.
Professional Bathymetric Survey Platform
Portable, autonomous, and built for real hydrographic fieldwork
Apache 3 Pro is designed for teams that need a practical hydrographic survey solution without moving to a larger and more complex vessel setup. It is especially attractive for shallow-water bathymetry, channel work, dredging support, river survey, bridge approaches, and water infrastructure projects.

Why It Stands Out
A compact turnkey USV system for efficient shallow-water hydrography
Apache 3 Pro is not just a small survey boat. It is a fully integrated hydrographic system designed to help operators launch faster, run autonomous missions, maintain measurement quality, and work safely from shore.
Its integrated navigation, built-in echosounder, autonomous route planning, obstacle avoidance, and real-time communications make it a strong option for organizations that need reliable bathymetric data without a large crew or a full-size survey vessel.
- Single-person transport and deployment
- Integrated D270 single-beam echosounder
- GNSS RTK + INS support for more stable navigation
- Millimeter-wave obstacle avoidance for safer autonomous work
Key advantages
Apache 3 Pro is designed to deliver practical field benefits for hydrographic surveyors, engineers, marine contractors, and environmental teams.
Integrated Survey Workflow
RTK positioning, INS, echosounder, camera, storage, and communications are combined into one professional USV platform.
Strong Shallow-Water Capability
The shallow draft and compact hull design help the Apache 3 Pro operate in environments where larger vessels are less practical.
Better Safety from Shore
Operators can perform bathymetric surveys remotely instead of placing crew directly in hazardous, narrow, or obstructed water areas.
Obstacle Avoidance Support
Built-in millimeter-wave radar helps detect obstacles ahead and supports safer autonomous navigation in survey missions.
Efficient Data Collection
EasySail software supports route planning, acquisition, and processing for a cleaner end-to-end workflow.
Integrated Hardware
Built-in technologies that improve productivity in the field
Apache 3 Pro combines multiple essential systems in one compact hydrographic platform so crews can work faster with fewer external components.
Smart Positioning and Navigation
Better measurement continuity near structures and under bridges
One of the main strengths of the Apache 3 Pro is its integrated GNSS RTK + INS navigation approach. This helps maintain more reliable course control and positioning continuity when satellite conditions are temporarily degraded.
That is especially useful in applications such as bridge approaches, channel crossings, culvert zones, infrastructure inspections, or operations near obstructions where conventional GNSS-only workflows can become less stable.
- Integrated positioning and heading
- INS support during temporary GNSS interruption
- Improved navigation stability for autonomous routes
- More reliable hydrographic data collection in difficult environments
Typical applications
Apache 3 Pro is suitable for shallow-water hydrographic and bathymetric workflows where portability, safety, and autonomous operation matter.
Rugged Hull and Water-Ready Design
Built for demanding hydrographic environments
Apache 3 Pro is built around a rugged compact hull with strong emphasis on shallow-water performance, impact resistance, and operational reliability. Official materials highlight its IP67 protection, anti-collision thinking, and unsinkable double-layered carbon-fiber-based hull concept.
Its semi-embedded motor design is particularly valuable in real field conditions because it helps protect the propulsion system, improves behavior around vegetation, and supports efficient movement in different water conditions.
- IP67 protection for harsh field conditions
- Shallow draft for tighter and shallower areas
- Better motor protection in difficult water environments
- Compact hull for easier transport and faster launch
Software Workflow
Mission planning, acquisition, and processing in one workflow
The Apache 3 Pro workflow is centered around EasySail for mission planning and autonomous control, and for sounding data recording and post-processing.
This helps operators plan areas, generate navigation paths, monitor missions in real time, manage sounding data, and export results for further use in third-party hydrographic or CAD/GIS workflows.
Apache 3 Pro FAQ
What is the CHCNAV Apache 3 Pro used for?
Apache 3 Pro is a compact unmanned surface vehicle designed for autonomous bathymetric surveys in shallow-water environments such as rivers, lakes, channels, reservoirs, and other inland hydrographic applications.
