AGS provides UAS geophysical data acquisition services and custom built UAS geophysical data acquisition systems using airborne robots for:
2
› resource exploration - mineral, groundwater, and hydrocarbon
› subsurface characterization - environmental and engineering
› buried object detection - unexploded ordnance (UXO)
› subsurface infrastructure delineation
› geoscientific mapping
1. Low Data Point Cost
2. Improved Productivity
3. Higher Definition
4. Greater Sensitivity
5. Access to difficult & risky areas
6. More Data Overall
7. Reduced Risk to personnel & public

Applications of UAS magnetometry
• Geological Mapping – lithology, structure, etc.
• Detecting and delineating undocumented and poorly documented wells.
• Detection and mapping of buried pipelines, etc.
• Detecting and mapping buried ferromagnetic objects and UXO.
9
Applications of Radio Frequency EM
• Geological Mapping – lithology, structure, etc.
• Precious and base metal exploration
• Fracture mapping for groundwater resources in crystalline rock.
• Contaminant plume delineation
• Detection and mapping of buried pipelines, metallic objects, etc.
10
Benefits of UAS magnetometry
Cost: ~ 20% of cost for a conventional ground magnetic survey.
~ 50% or less of the cost of a typical high resolution airborne magnetic (HRAM) survey.
Acquisition Rate: 10 to 20 times the daily coverage of a ground magnetic survey with equivalent or better spatial resolution.
50% of the daily coverage of a similar HRAM survey.
Data Quality:As good or better than a conventional ground magnetic survey.
Enhanced detail compared to a typical HRAM survey.
