Abstract (en)
[origin: WO2014195610A1] The invention relates to a metrology method and device for calibrating the geometry of a network of Nb stationary underwater acoustic beacons (11, 12, 13, 14) defining a field of beacons, implementing a moving body (20) comprising means for receiving acoustic signals from each of the beacons of the network, respectively. According to the invention, the metrology method includes the following steps: acquiring Nm series of Nb acoustic measurements of the relative distance between the moving body and each beacon of the network, respectively, during a movement of the moving body; calculating a numeric function C from the series of acoustic measurements of the relative distances and parameters representing relative positions of the beacons; executing an algorithm for minimising the numeric function C in order to deduce therefrom an estimation of the values of the relative position parameters of each of the beacons of the network.
