Apache 4 Pro

Hydrographic and Bathymetric Surveys USV

The APACHE 4 Pro is a versatile Unmanned Surface Vessel (USV) designed to support a wide range of hydrological survey tasks.

The APACHE 4 Pro is a versatile Unmanned Surface Vessel (USV) designed to support a wide range of hydrological survey tasks. It is compatible with various mainstream Acoustic Doppler Current Profilers (ADCPs) and also supports the CHCNAV HQ-400 Multibeam Echo Sounder (MBES) for underwater bathymetric surveys. The platform can be customized to carry water quality meters, side-scan sonar, and more.

Constructed with high-strength, high-modulus carbon fiber and HPT one-piece molding technology, the hull achieves a strength of up to 10 MPa, significantly enhancing its collision resistance. The motors are equipped with mesh covers, reducing the risk of deformation upon impact.

Rugged hull design

The APACHE 4 Pro features a titanium alloy mesh cover combined with hybrid water pressure conversion technology, significantly reducing the risk of entanglement by aquatic vegetation. If the motor does become entangled, the system triggers a software alarm to help ensure motor safety.

Anti-entanglement design

Versatile Instrumentation Compatibility

With a 50 kg payload capacity and a 24 cm central access shaft, the APACHE 4 Pro supports ADCPs such as the CHCNAV RiverStar Series, M9, RiverPro, and RioGrande. It also accommodates the CHCNAV HQ-400 multibeam echo sounder, side-scan sonar, and water quality monitors end-to-end survey solutions.

The APACHE 4 Pro features high-sensitivity, anti-interference transducers combined with residual vibration elimination technology. Its advanced bathymetric algorithms support adaptive parameter adjustment, enabling reliable performance in complex underwater terrain and diverse water environments.

Advanced Echosounder

The APACHE 4 Pro features an Android remote control that ensures reliable hydrographic and bathymetric survey operations. With both 4G and 2.4 GHz connectivity, it enables real-time monitoring and seamless vessel control. The EasySail app supports route planning, real-time data and video feedback, data collection, and post-processing.

Smart Controller

The APACHE 4 Pro supports an optional automatic sound velocity profiler kit, which can be controlled via the remote controller. The kit can be installed or removed in under one minute, providing a complete multibeam echo sounder solution for the USV.
