In order to detect satellite mobile telephones (M1, M2, M3) which are active in the vicinity of an observer, the uplink signals (Up) of the satellite mobile telephones (M1, M2, M3) which are active in the vicinity of the observer are received by means of a broadband receiver (E) at the location (T) of the observer, and then the locations of the satellite mobile telephones (M1, M2, M3) which are active in the vicinity of the observer are determined from the location information transmitted via these uplink signals (Up), and are displayed on an electronic map (K). |
