DRONE TIME DOMAIN ELECTROMAGNETICS

INTRODUCING THE FIRST UAV ELECTROMAGNETIC SYSTEM OF ITS KIND IN THE WORLD

DroneTDEM is our proprietary technique where we measure simultaneously the slowly varying field strength of the earth’s magnetic field and in addition, superimposed on this magnetic field, is also the magnetic signature of the fast-changing manmade induced currents in the subsurface.

Using this technique, we can model the ore body precisely in 3D in the ground as long as it is conductive or resistive. This will enable identification of precise target sites for test hole or well drilling.

FIXED WING VS UAV MAGNETIC DATA COMPARISONS

Lower flying height, slower flying speed and the MagArrow magnetometer sampling at 1000 Hz, 100 times faster than current magnetometers, results in a more detailed map.

FIXED-WING data sampling

50m flying height
100m line spacing
10 samples per second

UAV data sampling

25M flying height
25m spacing
1000 samples per second
