Magnetic Field Measurements (Video & Overview)
Radai delivers highly accurate drone-based magnetic total field and vector magnetic surveys. By installing cutting-edge magnetometers onto autonomous UAV flight platforms, we efficiently map complex subsurface structures to provide clear visualization of geological assets.So far, Radai provides the following magnetic survey services: Drone-based magnetic total field surveys, Drone-based vector magnetic surveys.
Technical Capabilities & Target Parameters
- High-precision fluxgate and potassium sensor integration
- Autonomous terrain-following altitude optimization (down to 10m)
- Simultaneous total field & multi-component vector recording
Radiometric surveys (Video & Overview)
We provide advanced 3D inversion of vector magnetic and electromagnetic data. By processing high-density aerial datasets, our processing team provides deep structural interpretations and geological depth models to assist targeting phases.
Radiometric surveys (Video & Overview)
Radai’s novel EM survey system provides information about the electrical conductivity of the subsurface. The applications of the EM system include geological mapping, mineral exploration, groundwater studies, geotechnical investigations, and environmental monitoring. The airborne system has the benefit of avoiding terrain obstacles and, thus, offers faster, safer, more cost-effective survey data.. (Read more)
Key concept
- Semi-airborne version uses fixed ground loop transmitter & airborne 3-component receiver towed by a VTOL drone
- Fully airborne version uses small (r<0.6m) transmitter loop attached to the towing drone
- Noise level < 20 fT 3 frequencies (2.3, 4.6, 9.2 kHz) 1 Hz sampling
- Depth of exploration 1-300 m
- Data post processing by 1D and 3D inversion
Data interpretation (Overview)
Radai provides advanced geophysical data interpretation services that transform drone-based magnetic, electromagnetic (EM) and radiometric measurements into actionable geological information. The services include data processing, spatial analysis, geological interpretation, anomaly identification, 3D modelling and integration of multiple geophysical and geospatial datasets to identify structures and prospective targets. The resulting maps, models and interpretations help mineral exploration customers prioritize targets, optimize follow-up surveys and drilling, and reduce exploration costs and uncertainty.
Radai offers high-resolution ground geophysical surveys designed to complement drone-based measurements and provide detailed information on priority exploration targets. Services include ground magnetic, electromagnetic (EM), and radiometric surveys, enabling more precise characterization of geological structures, conductivity, target depth and geometry, and variations in potassium, uranium and thorium. By integrating ground measurements with UAV datasets, Radai delivers a more comprehensive understanding of subsurface geology, helping to reduce exploration risks and improve mineral targeting and resource-development decisions.
