Method for searching a transmitter with a detector, which includes at least a first and a second antenna for receiving a transmit signal of the transmitter, wherein the transmit signal includes transmit pulses emitted with a certain transmit pulse period, as well as a position determining device for determining at least one orientation variation of the detector, comprising the following steps: a) detecting the vectorial magnetic field strengths ( Hv 1 meas, Hu 1 meas, Hv 2 meas, Hu 2 meas) of the field emitted by the transmitter in at least two dimensions for at least a first and a second measurement point relative to a reference axis of the detector carried by a searcher; further comprising the following steps for determining a position vector [p i], which represents the location of at least one measurement point relative to the location of the transmitter: b) detecting at least one orientation difference, φ 2 -φ 1, of the detector between an orientation of the reference axis of the detector in the first measurement point and an orientation of the reference axis of the detector in the second measurement point; c) assuming at least one geometric relation between at least the first and the second measurement point, based on an introduced geometric restriction for the movement of the searcher; d) assuming initial values for the position vector [p i] in at least two dimensions in at least the first and the second measurement point; e) assuming an orientation (α) of a transmitting antenna of the transmitter related to a first presettable reference direction; f) calculating the vectorial magnetic field strengths ( Hv 1 calc, Hu 1 calc, Hv 2 calc, Hu 2 calc) of the field emitted by the transmitter in at least two dimensions for at least the first and the second measurement point based on the assumptions according to the steps c) to e) as well as the detected orientation difference, φ 2 -φ 1, according to step b); g) calculating an error vector [g] between the vectorial magnetic field strengths detected in step a) and the vectorial magnetic field strengths calculated in step f); and h) numerically minimizing a function, E, of the error vector [g] calculated in step g) by altering the assumptions made in steps c) to e) until a presettable tolerance threshold, tol, for the function, E, of the error vector [g] is undercut. a) detecting the vectorial magnetic field strengths ( Hv 1 meas, Hu 1 meas, Hv 2 meas, Hu 2 meas) of the field emitted by the transmitter in at least two dimensions for at least a first and a second measurement point relative to a reference axis of the detector carried by a searcher; b) detecting at least one orientation difference, φ 2 -φ 1, of the detector between an orientation of the reference axis of the detector in the first measurement point and an orientation of the reference axis of the detector in the second measurement point; c) assuming at least one geometric relation between at least the first and the second measurement point, based on an introduced geometric restriction for the movement of the searcher; d) assuming initial values for the position vector [p i] in at least two dimensions in at least the first and the second measurement point; e) assuming an orientation (α) of a transmitting antenna of the transmitter related to a first presettable reference direction; f) calculating the vectorial magnetic field strengths ( Hv 1 calc, Hu 1 calc, Hv 2 calc, Hu 2 calc) of the field emitted by the transmitter in at least two dimensions for at least the first and the second measurement point based on the assumptions according to the steps c) to e) as well as the detected orientation difference, φ 2 -φ 1, according to step b); g) calculating an error vector [g] between the vectorial magnetic field strengths detected in step a) and the vectorial magnetic field strengths calculated in step f); and h) numerically minimizing a function, E, of the error vector [g] calculated in step g) by altering the assumptions made in steps c) to e) until a presettable tolerance threshold, tol, for the function, E, of the error vector [g] is undercut.
