Hydrographic survey USV L20

for oceanographic surveysfor bathymetry surveysautonomous

1. When equipped with a USBL, it can be utilized for secondary positioning in marine geophysical surveys; 2. With a single-beam depth sounder onboard, it’s capable of conducting water depth measurements; 3. Operation is via remote control or command station, with switchable modes. 4. The remote control facilitates the transition and management of the vessel’s dual power systems, as well as the operation of the bow thruster; 5. A range of navigational modes are selectable, including standby, station keeping, track angle, bow direction, queue, path point, and external control, with the flexibility for users totoggle between different settings as needed; 6. The vessel features two independent lifting mechanisms, allowing for separate control. Users can remotely manage the lowering and retrieval of the equipment’s wet end, with real-time depth monitoring displayed directly on the software interface; 7. Video, radar, and sensor data are live-transmitted for monitoring and alerting； 8. Radar and AIS sensors enable collision avoidance and navigation warnings； 9. Software settings allow for the establishment of navigation speed limits and electronic fences to prevent the vessel from entering hazardous zones; 10. The software supports the import of obstacle data and design survey line files, such as Preplot files (formatted in .SPS and .shapfile), and offers coordinate system conversion capabilities, making it suitable for operations in any local coordinate system;
