The Sailbuoy is a long endurance unmanned surface vehicle for the oceans.

Field proven to stay for months at sea, it navigates the oceans autonomously - transmitting back data at regular intervals. The Sailbuoy can be used for a wide variety of ocean applications. From measuring ocean and atmospheric parameters to tracking oil spills or acting as a communication relay station for subsea instrumentation. You can follow the Sailbuoy and update tracks in real-time from your computer, tablet or smart phone.

The SB Echo is a field-tested version of the Sailbuoy containing a EK80 (WBT) Simrad echo sounder with a 333 kHz split beam transducer. It is also equipped with oxygen, temperature and conductivity sensors. The transducer is gimbaled to ensure the best possible data. Extensive testing has been done in the fishing fields of north Norway showing good results. A total of 1500 km was travelled and 260 hours of echosounder data collected. The mission is part of the GLIDER project run by Akvaplan Niva.
