Hydrographic surveying USV APACHE 6

for underwater topographic mappingremote-controlledbathymetric monitoring

The CHCNAV APACHE 6 is an autonomous unmanned surface vehicle (USV) for high-resolution 3D bathymetric surveys, underwater object localization and offshore construction. It combines a stable triple-hull platform, adaptable dual/rotating powertrain and an Android remote control to deliver accurate survey data in complex flow environments.

Highlights

• Autonomous USV optimised for high-resolution 3D bathymetric surveys, underwater object localisation and offshore construction.
• Triple-hull design with detachable side floats for enhanced stability in strong currents.
• Dual/rotating propeller powertrain providing precise manoeuvring and a tight turning radius (~2 m).
• Android-based remote control with multi-link communication for real-time access to vessel status and survey data.

Main features

• Multibeam echosounder and LiDAR support (optional) for integrated high-resolution 3D data acquisition.
• Powertrain adaptable to complex flow environments: dual propellers with intelligent rotating mechanism for improved control.
• Optional automated Sound Velocity Profiler (SVP) kit, removable and controllable via remote to complete multibeam workflows.
• Onboard sensors: full GNSS + IMU positioning and 360° video camera.

Benefits and performance

• Multifunctional survey platform supporting MBES, singlebeam, LiDAR and camera sensors to deliver high-resolution bathymetry and object localisation.
• Stable tri-hull platform maintains data quality in currents and confined waterways.
• Fast deployment and field operation: removable SVP kit and Android remote control enabling operation without an external PC.
• Rotating propeller technology enables precise turns ideal for narrow channels and detailed surveys.

Use cases

• Dredging operations
• Port and harbour surveys
• Bridge and dam inspection
• River and lake hydrographic mapping
