Radai offers the optimal solution for modern day mineral and environmental explorations
It is well known that mineral and environmental explorations are painstaking processes that require plenty of time and funding. Traditionally, geophysical measurements are performed using airplanes or by deploying human resources to the field. Both methods have obvious benefits but also pose certain inconveniences by being either expensive, slow or practically challenging.
Radai solved a century-old problem by developing new processing software and installing the sensors on autonomous UAV systems. The solution proved to be faster, more cost-efficient, environmentally friendly and safer than any other existing technology. Data quality offered by Radai’s technology is fully comparable if not better than those of other existing options.
The benefits of denser line separation (200 m -> 50 m -> 25 m) clearly show the improvement in data resolution.
UAVs vs. ground surveys
Benefits of UAVs
- No terrain obstacles (e.g.,swamps, lakes, rivers) → full data coverage
- Fast; v = 10-20 m/s → 40-70 line-km per hour!
- Cost-effective (in terms of man-hours)
- Less sensitive to boulders & small anomalies
- Good GPS reception
- Reduced risk to humans
Benefits of ground surveys
- Strong response & enhanced resolution
- Heavy equipment
- Stop & go
UAVs vs. manned airborne surveys
Benefits of UAVs
- Low start-up, operation & maintenance costs
- Fast deployment – No need for airfields & strict aviation certificates for pilot & UAV – Multiple UAVs
- Flexible process – The flight plan can be easily changed during survey.
Benefits of manned airborne surveys
- Heavy payloads (more accurate instruments)
- Multiple surveys at the same time (e.g. EM, radiom.)
- Longer flight times & larger areas
- Smooth flight
- Tradition & routines (good data quality)
Tech Specs
Radai operates a high-performance magnetic survey system that is based on a fixed-wing drone with an electric engine. With flight times over two hours and simultaneous use of 2-3 drones, up to one thousand line-kilometers can be reached during a single day.
Presently, only total magnetic intensity and vector magnetic field are measured. The individual XYZ components of the magnetic field help data interpretation by reducing the ambiguity of the inverse solution. Therefore, Radai is developing an accurate 3-component (vector) magnetic survey method.
Radai is also developing a novel electromagnetic (EM) survey system utilizing a 3-component EM receiver carried by a multicopter. The EM system provides information about the electrical properties (conductivity and permittivity) of the subsurface.
The EM data, together with magnetic field, provide essential information for geological mapping and mineral exploration.
