A method and a device for determining the changing position of a mobile transmitter in a three-dimensional space is proposed in which transmitted signals are issued at a pre-determined frequency from a mobile transmitter, wherein a plurality of receivers receive said transmitted signals. An evaluation device evaluates the received signals for generating correlation curves between the transmitted and the received signals. From the curves of magnitude versus time, TOA values are determined, and from curves in the complex plane, phase values are determined using the time information from the TOA values. The position of the mobile transmitter is calculated as a function of TOA values and of phase or phase difference values.
