SM-U1

The Surveying M SM-U1 Swift USV is a next-generation unmanned surface vessel designed for high-accuracy hydrographic surveys across rivers, lakes, reservoirs, ports, and confined water environments. Weighing only 16 kg and measuring 80 cm in length, SM-U1 offers exceptional portability and single-person deployment, including transport via a compact trolley case.

Equipped with a 120-meter depth single beam echosounder, the system delivers centimeter-level vertical precision with a beam angle of 8°. A millimeter-wave radar enables real-time obstacle detection up to 40 meters with automated avoidance responses at close range. The dual-ducted high-thrust propellers provide 6 m/s top speed and zero-turn-radius maneuverability.

The vessel integrates full-constellation GNSS with dual-antenna RTK positioning and supports both online (4G, UHF) and offline (PPK) workflows. The onboard intelligent navigation system supports auto-routing, remote mission planning, visualized data display, and automated return functions.

Its IP-rated composite body, removable 24V 40Ah lithium battery, and built-in 5.5-inch screen controller with a 2 km range round out a complete field-ready system built for mobile survey crews and mission-critical bathymetric work.
