JBUAS  & Offshore Wind

JBUAS teamed up with AIRBORNE PLATFORMS UK LTD to execute a 6km UXO clearance project over varied terrain, including undulating ground, fences and gates, hedges, and many different crop fields.

The Right Choice
The key contractor for the cable laying project was keen to see zero harm to the crops so damage could be avoided, along with any potential compensation payments. The airborne R4 magnetometer system was therefore selected as the system of choice. Cart or walked-based approaches were deemed too risky, and when the final economics were worked out, the use of the airborne system was a foregone conclusion.

Equipment Used
The airborne system comprised of:

– M300RTK drone (UAV)
– UgCS Pro (Survey Automation software)
– UgCS SkyHub 3 Onboard Computer
– UgCS True Terrain Following system (TTF v2)
– SENSYS MagDrone R4 Airborne Magnetometer

TTF, RTK, and R4
With a sample rate of 200Hz, the fluxgate sensors onboard the R4 enable fast speeds to be flown. The R4 also benefits from a sensor spaced every 50cm meaning its pass width is an impressive 2.5m. With RTK-corrected GPS data sent directly to the R4 from SkyHub, very precise flight lines (~1cm) are possible. Add to this the TTF system, which delivers the capability to perform low flying (below 1m if appropriate); the R4 can identify smaller targets in the near-surface.
