Beschreibung
Zusammenfassung:	A system and method permitting accurate position determination and measurement of the location of a subterranean directional drilling tool, in sensitive or hard-to-reach surface areas. A rotating magnetic target is integrated into the drill string. A triaxial magnetometer is mounted to a UAV capable of hovering in position in a hard-to-reach area in which it is desired to determine the location of the drilling tool. The magnetometer, in position over the location, will determine the location of the directional tool based on the measurement of the magnetic field therefrom, and the location of the subterranean directional tool in relation to the drone or a terrestrial based location can be determined.
