Abstract: A method of determining a position of a mobile telecommunication device (10) which transmits a signal (S) to base stations (1, 2, 3, . . . ) connected by a data link (8) comprises the steps of: correlating the received signal (S) and a reference signal (S′) so as to produce a correlation for each base station, detecting a maximum in each correlation, which maximum is indicative of a time of arrival of the signal (S) at the respective base station, and using the respective times of arrival and the distances (D1, D2, . . . ) derived therefrom to derive a location of the mobile telecommunication device. The method uses receivers (21, 22, . . . ) coupled to a data network (7), each receiver (21, 22, . . . ) deriving the reference signal (S′) from the received signal (S). Each base station may select, if it receives multiple reference signals, the reference signal (S′) having the highest quality.
