THURN QuickDip™ System for Aerial Drone Dipping Sensors Takes Off
A cutting-edge new system for autonomous airborne hydrographic survey has been launched by THURN Group. The THURN QuickDip™ system of data collection uses aerial drones to carry Valeport sensors on pre-planned survey routes to deliver an efficient and repeatable method of gathering highly accurate survey data from inaccessible or dangerous waters.
UK-based THURN Group developed the innovative QuickDip technology for inland and coastal waterways to offer a range of benefits including: rapid data collection from multiple sites of interest, repeatable map- based surveys to monitor change detection, the ability to safely collect data from difficult-to-access and dangerous waters as well as restricted- access waters, such as reservoirs.
THURN QuickDip™ integrated drone- based system uses a Valeport sensor, a cable, a rotocopter drone and UgCS SkyHub/True Terrain Following (TTF) hardware - from leading software developer for unmanned aerial systems SPH Engineering. THURN’s integration of hardware and software allows the drone to fly at an accurate fixed height over water using a map- based pre-programmed autonomous survey pattern and dip the sensor into the water to take readings.
As Tom Hiller, General Manager, THURN Group commented there are many options with the QuickDip technology: “Using a drone to deploy sensors has distinct advantages over a boat; it is compact as well as easy to transport and deploy. Drones can be used in any location where there is a small area for take-off and landing near the surveyed water. What makes this new system so exciting for autonomous data collection
is a drone’s ability to precisely follow planned survey lines using the map- based interface in UgCS, and therefore deliver accurate, repeatable surveys in previously difficult to access waters.
“We’re launching the THURN QuickDip with the miniSVS and Hyperion range of Valeport sensors which are respected for their high levels of accuracy, but this is just the first in an expanding range of drone-dipped sensors for coastal and inland water survey. We encourage manufacturers to who feel they have clients who could dip their sensors from a drone to get in touch with us at THURN.”
The compact and robust Environmental range of optical sensors from leading oceanographic and hydrographic instrument manufacturer, Valeport, are being offered as part of the QuickDip system, including the Hyperion range of environmental sensors for the measurement of Turbidity, Chlorophyll a, Fluorescein, Rhodamine or Phycocyanin as well as their popular miniSVS and SWiFT SVP.
THURN Group has collaborated closely with UgCS (SPH Engineering) to develop the QuickDip range of dipping
sonar and sensor products. Chief Technology Officer at SPH Engineering, Alexey Dobrovolskiy commented: “We are happy to see our partners THURN Group extend the range of sensors supported by UgCS Industrial Solutions with the help of the SkyHub SDK. Particularly, it is great to see the integration of the high-end sensors from Valeport with the THURN QuickDip.”
THURN Group provides underwater survey technology, offshore project consulting and training to inland waterway authorities, engineering companies, ports, oil and gas, and renewables clients worldwide.
