Method of determining the position of a detector disposed at the bottom of the sea. Method of determining the position of a detector disposed under the sea, comprising the following steps: emission of N waves from N emission points, recording of the propagation time of said wave between each emission point and the detector, determination of P time intervals Ti, with Pâ ¥1 such that, for each time interval Ti, there exist Mi emission points, Mi â ¥3 for 1â ¤ i â ¤P, whose propagation times lie in the said time interval, determination for each time interval Ti of the circle which passes closest to the Mi points whose propagation time lies in said time interval, determination of the position of the detector as being the barycentre of the P centres of the circles determined previously. |
