Bathymetry with BlueBoat USV – accuracy and efficiency in Latvian waters
In modern hydrography and underwater research, time and accuracy are the determining factors. While bathymetry measurements (mapping the bed relief) used to require large resources, crew boats and complex logistics, today the solution is more compact, smarter and more accessible.
Dronelab Ltd, authorized Blue Robotics distributor in Latvia, introduces BlueBoat – an innovative unmanned surface vehicle (USV) designed specifically for hydrographic surveys and robotics projects.
What is BlueBoat?
BlueBoat is not just a remote-controlled boat. It is a high-performance catamaran-type USV, designed to ensure maximum stability even in changing weather conditions. Its main task is to autonomously scan the seabed using echo sounders and other sensor systems.
Integrable sensors: From simple mapping to scientific research
The biggest advantage of BlueBoat is that open architecture, which allows it to be equipped with a wide range of sensors depending on the task at hand:
| Sensor type | Uses and benefits |
| Single Beam Echo Sounder (SBES) | Ideal for basic bathymetry, depth measurement in channels and rivers. Provides an accurate depth point network at low cost. |
| Multibeam echo sounder (MBES) | For professional and high-resolution 3D bed mapping. Allows you to obtain a complete “cloud” of data, identifying even the smallest objects on the bed. |
| Side scan sonar (SSS) | Used to search for sunken objects, pipelines or archaeological finds. Provides a photo-like visualization of the seabed. |
| Water quality probes | Sensors that measure temperature, turbidity, pH, oxygen content, and conductivity. Essential for environmental monitoring and pollution control. |
| ADCP (Acoustic Doppler Current Profiler) | Allows for accurate measurement of water flow speed and direction at different depth layers – critical for port engineering. |
| Magnetometers | For detecting metal objects (such as unexploded ordnance or cables) beneath bed sediments. |
Technical parameters that highlight BlueBoat:
- Design: The catamaran hull provides excellent hydrodynamics and stability, reducing water resistance and energy consumption.
- Autonomy: Thanks to its powerful batteries, BlueBoat can work for up to 60 hours, making it an ideal tool for mapping large areas.
- Open source platform: BlueBoat operates on BlueOS and ArduPilot bases that allow the user to fully customize missions, routes, and integrate specific equipment.
- Navigation accuracy: Integrated GPS and the ability to add RTK (Real-Time Kinematic) The system provides measurement accuracy of up to a few centimeters.
Why choose USV for bathymetry measurements?
Traditional bathymetry is often limited in shallow waters or areas with dense vegetation. BlueBoat solves these problems:
- Safety: There is no need to send people to dangerous places (near dams, industrial zones).
- Economy: Low operating costs – no fuel or large crew required.
- Data quality: Thanks to the stable performance and low noise level, echo sounder data is cleaner and requires less post-processing.
Application in Latvian conditions
In Latvia, BlueBoat is perfect for:
- For regular inspection of port waters and control of dredging works.
- For mapping the beds of inland waters (lakes, rivers) for the needs of local governments and environmental services.
- For archaeological research and searching for sunken objects.
