FIELD: physics.
SUBSTANCE: coordinate system is created from GIB buoys with base length of 1-3 km, which receives ping signals of underwater objects, synchronised with GPS clocks and time-spaced. Through correlation reception, the GIB buoys determine lag time from each object and relay these data to a control station. Based on the lag time and data on hydrostatic pressure on the underwater object, the control station calculates coordinates and displays the position of each object.
EFFECT: high accuracy and reliability of determining coordinates of an underwater object, increase in number of controlled objects.
