Claim 17:
18. The method of claim 14, wherein said data representative of difference in times of arrival of modulation patterns of the signals comprises an ambiguity, wherein the method comprises:
using the first estimate êSrc of the physical location of the source to determine Δ{circumflex over (t)}m,n, wherein Δ{circumflex over (t)}m,n is an estimate of data representative of difference in times of arrival of the modulation patterns of the signals,
determining said one or more second estimates êSrc of the physical location of the signal source based on a relationship relating said differential phase differences ΔΔφm,n to the position data of the receivers and to the physical location of the signal source, and
a relationship relating said estimate of the data representative of difference in times of arrival of the modulation patterns Δ{circumflex over (t)}m,n plus a model k.PRI of said ambiguity to the position data of the receivers and to the physical location of the signal source, wherein k is an integer selected such that said one or more second estimates êSrck are within said accuracy area and wherein PRI is a pulse repetition interval of the signal S.
