Automated data capture of the underwater world like never before
The apache 4 MARINE SYSTEM
The Apache 4 is a compact yet highly capable Unmanned Surface Vessel l designed by CHC Navigation to deliver precise, reliable results, no matter how challenging the environment.
Purpose-built for areas that are difficult or hazardous for human access, the Apache 4 offers a highly portable solution without compromising performance. This means you can collect high-quality hydrographic data like never before.
It stays on course and captures precise data, even in tough conditions. With dual GNSS and IMU integration, you get reliable positioning when GPS signals drop off. Autonomous navigation takes the pressure off, letting you safely survey hard-to-reach areas without setting foot in the water. Paired with single or multibeam echo sounders, it delivers high-resolution depth profiles from just 15 cm to 200 m deep, with pinpoint ±0.01 m accuracy.
Features
Thanks to a GNSS + IMU positioning system, the Apache 4 stays on course even in turbulent flow or when GPS signals are limited. This means highly accurate cross-sectional data, especially important for flood modelling and riverbed profiling.
At the start and end of ADCP observations, the vessel can hover steadily in place, reducing noise in flow estimations and increasing data reliability.
With depth range capabilities from 0.15 to 200 meters and ±0.01 m accuracy, this unit provides detailed water depth profiles and can verify or complement ADCP tracking data.
Don’t let its size fool you: this vessel can carry up to 35 kg of payload, including ADCP sensors, multi-beam echo sounders, side scan sonar, and water quality monitors.
With up to 8 hours of endurance on a single charge and hot swappable batteries, teams can complete large surveys in one go -no mid-mission swaps or delays.
Using CHC’s dedicated Easysail app and Android control system, operators can plan missions, view live video of the area with built-in 360 camera, data feeds, and make real-time adjustments -all from shore.
With millimeter-wave obstacle detection, auto-return on low battery or lost signal, and a triple-hull carbon fiber design (IP67 rated), safety and reliability are built into every survey.

GNSS SENSORS & SURVEYING ROVERS
CHCNAV is redefining GNSS positioning with systems built for surveyors, engineers, and construction professionals who demand accuracy and reliability. By combining multi-constellation satellite tracking, intelligent tilt compensation, and rugged, field-ready design, our GNSS sensors deliver fast, precise results. Using signals from multiple satellites, the sensors calculate their exact location through triangulation, analyzing the time delay from at least four satellites. To push accuracy even further, they leverage Real-Time Kinematic (RTK) correction data from a base station, reducing atmospheric errors and achieving centimetre-level precision.
The result is highly accurate latitude, longitude, and altitude coordinates that integrate seamlessly with mapping software and field tools. Whether for surveying, construction, or navigation, CHCNAV’s GNSS solutions simplify complex tasks and deliver dependable performance, even in the most demanding environments.
