CHC Navigation Introduces APACHE 4 PRO: A Multi-Purpose USV for Comprehensive Hydrographic Surveys

Shanghai, China – January 1, 2026 – CHC Navigation (CHCNAV), a global provider of geospatial solutions, announces the launch of the APACHE 4 PRO, a versatile Unmanned Surface Vessel (USV) designed for a wide range of hydrographic and bathymetric survey applications. By integrating a rugged hull design, versatile instrument compatibility, and intelligent navigation capabilities, the APACHE 4 PRO provides a reliable platform for detailed underwater mapping and environmental monitoring.

Adaptable Platform for Diverse Survey Payloads

The APACHE 4 PRO is engineered for mission flexibility. The USV seamlessly accommodates various mainstream Acoustic Doppler Current Profilers (ADCPs) and integrates with the CHCNAV HQ-400 Multibeam Echo Sounder (MBES). This allows survey professionals to configure the vessel for specific tasks, from bathymetric mapping and current profiling to water quality analysis, enabling complete end-to-end survey workflows.

Rugged Hull and Anti-Entanglement Design

The APACHE 4 Pro’s triple-hull structure is built from high-strength carbon fiber using one-piece molding technology, providing resistance to collisions and impacts. Protective mesh covers over the propulsion system reduce the risk of mechanical damage during operations. An integrated titanium alloy mesh and hybrid water-flow design help prevent entanglement with vegetation; in case of obstruction, on-screen alerts notify the operator to take corrective action.

Intelligent Operation and Real-Time Control

Equipped with adaptive navigation algorithms and anti-interference transducers, the APACHE 4 PRO ensures precise data collection in complex underwater terrains. Operators can plan missions, monitor progress, and adjust parameters in real time via the Android-based EasySail app, which offers 4G and 2.4 GHz connectivity for remote control. Features such as automated route planning, obstacle detection alerts, and dual GNSS antenna positioning enhance safety and efficiency during autonomous deployments.
