Abstract
A method of determining the position of a detector disposed under the sea, comprising the following steps: emit N waves from N emission points, record the propagation time of said wave between each emission point and the detector; determine the P time intervals Ti, with P≧1 such that, for each time interval Ti, there exist Mi emission points, Mi≧3 for 1≦i≦P, whose propagation times lie in the time interval, determine for each time interval Ti of the circle which passes closest to the Mi points whose propagation time lies in said time interval, and then determine the position of the detector as being the barycenter of the P centers of the circles determined previously.
