The THURN SpeedSampler System provides all the tools for your USV sampling requirements. Supplied with a range of different marine sensors all of which come fully integrated.

This system was designed to enable remote surveys, keeping people out of the water and minimising risk. This decreases survey time and enables sampling in previously inaccessible and dangerous waters.

With easy to use industry standard software options this will help solve your water management and safety problems. The software will track and display the position of the USV in real-time, with a real-time data feed option.
