Positioning method/device for locating a source emitting electromagnetic radiation uses interfaces to detect a position and to exchange data about locating reference and target sources

摘要

A passenger (1) carries a mobile device (MD) (2) like a mobile telephone or a personal data assistant and boards a means (3) of transport like a bus, where a reference source (RS) (4) is installed in the form of a bus driver's mobile telephone. If the bus has a global positioning system (7), the RS position can be determined more exactly than with field strength measurement.
