CHC Navigation

Yes, the APACHE 4 is an Unmanned Surface Vehicle (USV) that supports a wide variety of Acoustic Doppler Current Profiler (ADCP) systems available on the market. The APACHE 4 USV brings together the best of high-accuracy positioning and automated navigation control technology, built around the operator's habits when conducting ADCP hydrographic cross-section flow measurements. The measurement can be taken close to the shore as the Apache 4 has a draft of only 10 cm. The built-in adaptive water flow and hovering navigation technology significantly improve flow estimation accuracy. Even when GNSS positioning might be degraded by obstructed environments, the internal GNSS+IMU module continues to provide reliable position and heading for the ADCP and autopilot controller.

APACHE 4 provides a reliable solution that eliminates the construction and maintenance costs associated with traditional ADCP's ropeway towing systems, overcomes irregular navigational conditions that lead to poor data results, compensates for the resulting loss of ADCP measurement data and maintains heading accuracy in challenging environments. APACHE 4 solves these challenges and allows for high accuracy hydrological and hydrographic surveys.
