Hydrographic and Bathymetric Surveys USV
The APACHE 4 USV is optimized for hydrological studies, supporting a range of ADCP and compact multi-beam systems. Its shallow draft, high accuracy, and stable hovering make it ideal for measuring water flow velocity and discharge. Compact and easy to handle, it ensures effortless site management, safe launches, and convenient car transport. With integrated GNSS+IMU technology, it provides reliable positioning and heading, enhancing ADCP and autopilot functionality for precise water flow analysis.
FEATURES
Integrated adaptive water flow straightline and hovering technology.
The automatic control system enables the APACHE 4 to navigate in a straight line along the cross-section, adapting safely to changes in flow, turbulence and other conditions. Stable positioning and heading, provided by the GNSS+IMU module, enable precise navigation. Hovering positioning technology enables the APACHE 4 to maintain a stable position in turbulent waters at the start and end points of ADCP observation, improving the accuracy of flow estimation.
COMPATIBLE WITH LEADING ADCPS
Up to 40 kg payload with broad system integration
Designed for cross-sectional flow measurement, the APACHE 4 is compatible with ADCP models such as RiverStar, M9, RTDP 1200, RiverPro, and RiverRay. It offers integrated support for positioning, power, waterproofing, and 4G data transmission.
OPTIONAL SENSOR INTEGRATION
Modular access for expanded sensor compatibility
The APACHE 4 features a central shaft for mounting additional instruments, including optional CHCNAV multibeam echosounders. Its modular design supports a variety of applications, from hydrological surveys to disaster response and harbor infrastructure work.
INTELLIGENT ANDROID REMOTE CONTROLLER
Real-time data access and mission control
The APACHE4 Android-based controller enables reliable operation via 4G and 2.4 GHz connectivity. Paired with the CHCNAV EasySail app, it supports real-time data monitoring, video feedback, route planning, and post-processing.
