Faster Deployment, Greater Ease of Use, and Operational Improvement over Traditional Boats. GPASEABOTS, a GPAINNOVA Group company settled in Barcelona and specializing in marine robotics and solutions for calm water operations, has shown that is possible to carry out express multibeam bathymetries in record time without compromising quality.Read more
For that purpose, GPASEABOTS has equipped its most versatile unmanned surface vehicle (USV), the SB 100 PRO model, with Wassp S3r by Furuno-ENL, one of the most cost-effective mapping Multibeam sounder on the market. SB 100 PRO has been designed and manufactured under the "Ready to nav" concept; thanks to its ease of transportation and use, it can replace traditional boats in sheltered waters, where accuracy in the results prevail over covering large areas of water.
A further advantage of this multipurpose platform is its excellent autonomy —up to 3 hours —, which enables it to be used in long-lasting operations. Additionally, its autopilot function allows automating routes for data acquisition.
GPASEABOTS was recently required to carry out a Multibeam bathymetry at Port of Barcelona, one of Europe's major ports in the Mediterranean. This kind of commercial harbours needs constant control of the draught of the entire surface of the port since this avoids running aground and problems with the boats that enter and leave the area.
An SB 100 was carried to the port in the boot of a common car, together with the control station, the control unit and the batteries. Once there, technicians unloaded the boot and switched on the devices, the aquatic drone, the ground station and the controller. These steps were followed by a quick connection to a Real-Time Kinematic (RTK) base or GNSS receptor, to get the RTK corrections for the GPS.
After placing the USV on the water surface, which only takes 10 seconds, technicians were able to obtain high-quality results in less than 20 minutes.
