The Apache3 is a portable, shallow-draft USV with a single-beam echo sounder for bathymetric surveys of lakes, inland rivers and coastal areas. Seamless 4G communication removes traditional base-station and transmission-distance limits, while dual GNSS positioning/heading and an IMU allow uninterrupted survey even when passing below bridges. High-efficiency 5 m/s motors and absolute straight-line technology keep it on a pre-set course in autonomous mode under adverse currents.

Why the CHCNAV Apache3 USV
Reliable positioning
Dual GNSS positioning and heading plus an IMU sensor deliver consistently high accuracy even during temporary GNSS outages while passing under bridges, eliminating outliers.
Survey in most water conditions
High-efficiency DC-injection rotary motor technology provides a 40% increase in energy conversion efficiency, with an anti-collision, anti-corrosion design resistant to a month's seawater immersion.
Absolute linear technology
High-precision GNSS positioning and heading maintain a perfectly straight course in complex currents, and the sub-1 m pocket-hull supports shoals, channels and shallow rivers without running aground.
Easy connectivity
Seamless 4G communication removes the limitations of traditional network bridge base stations and transmission distances.
