Abstract
The present invention relates to a method and arrangement for positioning at least two devices, a first and a second device relative each other. The method comprises: transmitting a number of magnetic pulses with the first device, detecting said pulses with the second device, based on said detected pulses generating a number of virtual planes, and determining a crossing line between said planes corresponding to a direction between said devices.
