The problem of remote estimation of pulse source coordinates using relative delays of the signals accepted by hydrophones of radiobuoys in spaced points is considered. Location coordinates of radiobuoys are defined by GPS/GLONASS navigation with some known error. To decrease the estimation inaccuracy of pulse source coordinates the redefined system of interval equations for four signal receivers is considered. Settlement ratios are made. Configurations of placement of signal receivers when inaccuracies of coordinates are sufficient are defined by mathematical simulation. Mathematical simulation results and results of experiments in shallow water area by remote estimation of pulse source coordinates are given.
