A method and system for geolocating a wireless communication unit (410) in an asynchronous wireless communication system (400) are provided. The method comprises receiving measurements Tm(i), Tm(j) of the timing of signals received by one or more wireless communication units (410) from one or more pairs of base stations B(i),B(j). Differences dTb(i,j) are calculated between base station timing offsets Tb(i), Tb(j) for pairs of base stations B(i), B(j). The differences dTb(i,j) are iteratively corrected, to derive a final set of differences dTb(i,j). A synchronous geo-location technique is applied to the final set of differences dTb(i,j), to geo-locate a wireless communication unit (410). |
