Rugged hull design
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.
Anti-entanglement 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.
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.
Advanced Echosounder
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.
Smart Controller
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.
Automated SVP Measurement
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.
High Precision Multi Purpose ADCP
The RiverStar 3600D ADCP delivers high accuracy in both shallow and deep water environments. With a 9-beam configuration and a 600 kHz central depth measurement, it performs reliably across a wide range of water conditions, from slow to fast currents and varying depths. When integrated with the CHCNAV APACHE 4 Pro USV, it streamlines operations by requiring only one vessel and one remote controller, enhancing efficiency in hydrological surveying.
