Undertaking the UXO survey
Equipped with triaxial fluxgates with a 200mhz sampling rate to minimise noise and discern targets accurately. The UAV can identify targets up to 4m below the ground level, with a max speed of 50mph, a climb rate of 2 metres per second, and can operate in wet and dry conditions. The UAV is programmed to autonomously follow predetermined waypoints and uses lasers to automatically adjust its altitude to the undulations of the environment.
Brimstone met the complexity of the projects with guile; managing the bird nesting seasons, challenging access and egress, and overcoming the general difficulties of working in a remote and scientifically sensitive area, in all weathers. Whilst the project had its complications, we successfully mitigated the UXO threat throughout the duration of the works.
Several items of ordnance were safely recovered from the worksite without incident, including projectiles, mortars and small arms ammunition. Through data analysis, we identified potential UXO targets and operated a mark and avoid strategy to help keep works on track.
Supporting the environmental recovery at Dartmoor
Through the combined efforts of South West Water, the University of Exeter, the Duchy of Cornwall and Brimstone, Dartmoor is on track for peatland recovery, improving biodiversity, reducing greenhouse emissions and improving the health of local water supply.
