Apparatus and method for finding a device

An apparatus and a method for finding a device, whereby at least one magnetic dipole, arranged in the area of the device, rotates about a rotation axis extending at an angle of >0° to the device length axis, the three time-dependent magnetic-field components Hx(t), Hy(t) and Hz(t) are detected, a...

Beschreibung
Zusammenfassung:	An apparatus and a method for finding a device, whereby at least one magnetic dipole, arranged in the area of the device, rotates about a rotation axis extending at an angle of >0° to the device length axis, the three time-dependent magnetic-field components Hx(t), Hy(t) and Hz(t) are detected, and the position, the orientation of the device axis and/or the roll angle of the device is calculated from this.
