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 is 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.
