SL20
Compact USV for Inland Waterway Bathymetric survey and Water discharge measurement
SL20 USV: One-Person Operation, Zero Hassle
The SL20 USV is specially designed for ease – of – use. A single operator can handle it effortlessly, whether for quick bathymetic survey in coastal areas or water discharge measurement in narrow waterways. Its small size means it can be simply loaded into a car, enabling you to reach remote survey sites with ease.
Rugged Architecture for Field Operations
The SL20 is a thoughtfully designed compact USV built for real-world use. Every component, from the hull to the propulsion system, was engineered for durability and efficiency.
Compact Portability
The SL20 USV features a carbon-fiber hull (1.05m×0.55m×0.38m, 17kg) — compact as a golf travel bag and light enough for one-handed lifting.
Shallow – Water Navigation
With only 15cm draught, SL20 can navigate and operate effectively in narrow inland waterways, shallow rivers, and coastal areas where conventional vessels cannot access.
Tangle Free Propulsion
Powered by a debris-resistant waterjet thruster, SL20 reaches 8 knots while avoiding tangles in weeds and floating obstacles—ideal for messy shallow waters.
Enduring Operation and Quick Swap
With 6-hour endurance @ 3 knots and field-swappable batteries, SL20 powers full-day surveys without downtime.
Dual Control Options
The SL20 USV offers two control options, being operable via remote control for precise human intervention and equipped with an autopilot system for autonomous navigation and task execution.
- Radio Remote control with handheld terminal, communication range up to 1km.
- Autopilot under autonomous navigation, communication range up to 2km.
Wet Payload Flexibility
SL20 equipped with 177mm diameter moon pool for instruments installation, the mounting brackets for instruments like echo sounder, ADCP, RTK GPS could be customized designed.
