Abstract
A transmitter which emits at least two electromagnetic fields. An amplitude of each of the at least two electromagnetic fields has an anisotropy in one plane. An angular arrangement of the receiver relative to the transmitter is determined based on the amplitude of the at least two electromagnetic fields at the position of a receiver.

A method comprising:
- activating a transmitter surrounded by a specified surrounding region to emit at least two electromagnetic fields, wherein an amplitude of each of the at least two electromagnetic fields has an anisotropy in one plane, wherein the anisotropy is statically aligned in the plane;
- obtaining magnetic field measurement data, which indicate the amplitudes of the at least two electromagnetic fields at the position of a receiver;
- and
- determining an angular arrangement of the receiver with respect to the transmitter based on the amplitudes of the at least two electromagnetic fields at the position of the receiver;
- and
- determining whether the receiver is located inside of the specified surrounding region of the transmitter based at least on the determined angular arrangement of the receiver with respect to the transmitter.
A control apparatus of a transportation vehicle, wherein the control apparatus is configured to carry out a method that activates a transmitter surrounded by a specific surrounding region to emit at least two electromagnetic fields, wherein an amplitude of each of the at least two electromagnetic fields has an anisotropy in one plane, wherein the anisotropy is statically aligned in the plane,
- wherein the method obtains magnetic field measurement data, which indicate the amplitudes of the at least two electromagnetic fields at the position of a receiver,
- wherein the method determines an angular arrangement of the receiver with respect to the transmitter based on the amplitudes of the at least two electromagnetic fields at the position of the receiver, and
- wherein the method determines whether the receiver is located inside of the specified surrounding region of the transmitter based at least on the determined angular arrangement of the receiver with respect to the transmitter.
A transportation vehicle comprising:
- a first transmitter;
- a second transmitter;
- and
- a control apparatus configured to carry out a method that activates the first transmitter to emit at least two electromagnetic fields, wherein an amplitude of each of the at least two electromagnetic fields has an anisotropy in one plane, wherein the anisotropy is statically aligned in the plane, wherein the method obtains magnetic field measurement data, which indicate the amplitudes of the at least two electromagnetic fields at the position of a receiver, wherein the method determines an angular arrangement of the receiver with respect to the first transmitter based on the amplitudes of the at least two electromagnetic fields at the position of the receiver, and wherein the method determines whether the receiver is located inside of the specified surrounding region of the transmitter based at least on the determined angular arrangement of the receiver with respect to the transmitter,
- wherein the first transmitter has at least three coils arranged in a plane, wherein the second transmitter has a single coil.
