Abstract
A determination of a spatial position of a transmitter which emits a wireless signal is provided. A receiver which moves relative to the transmitter receives the wireless signal and analyses a Doppler shift in the received signal. Information is generated for specifying possible spatial positions of the transmitter based on a point of time when a sign in the Doppler shift changes. In this way, a very simple and efficient determination of possible locations of the transmitter can be achieved.
