Drone-based vector magnetic surveys

In addition  to total magnetic intensity, Radai measures vector magnetic field. The individual XYZ components of the magnetic field help 3D data interpretation by reducing the ambiguity of the inverse solution. XYZ data also helps identifying remanent magnetization.
