Monitoring USV APACHE 4 PRO

for underwater topographic mappingremote-controlledmulti-sensor

The CHCNAV APACHE 4 PRO is a versatile Unmanned Surface Vessel (USV) for hydrographic and bathymetric surveys, configurable to carry multibeam echo sounders, ADCPs and a variety of survey sensors. The platform pairs a one-piece carbon-fiber hull with anti-entanglement protection and an Android-based remote controller for reliable field deployment.

Highlights

• Configurable sensor platform: supports MBES (e.g., CHCNAV HQ-400), SBES, side-scan sonar, ADCPs and water quality sensors.
• Precise navigation: integrated GNSS + IMU for accurate positioning and heading during surveys.
• Android remote control: EasySail app with route planning, real-time data/video feedback and mission management over 4G and 2.4 GHz.
• Anti-entanglement design: titanium-alloy mesh protection and hybrid water-pressure conversion reduce vegetation entanglement risk.

Main features

• Configurable payload bay and central access shaft (Ø 24 cm) for ADCPs and instruments.
• Built-in SBES (single-beam) for standard depth measurements; optional CHCNAV HQ-400 MBES support.
• Rugged carbon-fiber one-piece molding hull for improved collision resistance.
• Smart controller: Android-based remote with 4G/2.4 GHz connectivity and real-time telemetry.

Benefits & Performance

• High instrumentation versatility: up to 50 kg payload for ADCPs (RiverStar series, M9, RiverPro, RioGrande), MBES and additional sensors.
• Advanced echosounder performance: high-sensitivity, anti-interference transducers with vibration elimination and adaptive bathymetric algorithms.
• Improved field uptime: anti-entanglement motor protection and software alarms to protect propulsion if fouling occurs.
• Optional automated SVP kit: removable in under one minute and controllable via the remote controller for accurate sound-velocity profiling.

Use Cases

• Water resource and hydrological surveys
• Channel dredging monitoring
• Bathymetric mapping in rivers, lakes and shallow coastal zones
• Emergency response and rapid-deployment survey missions
