METHOD FOR DETERMINING LOCATION OF UNDERWATER OBJECT AND SYSTEM FOR IMPLEMENTING METHOD Russian patent published in 2025 - IPC G01S5/08 

FIELD: marine navigation.

SUBSTANCE: section of the bottom surface, above which the underwater vehicle is located at the time of detecting or leaving the object under water, is presented in the form of a plurality of values of the measured depths, and the location of the object detected or abandoned by the underwater vehicle when re-entering its location is determined by establishing the identity of the combinatorial configuration, that is a combination of values measured during detection or abandonment of the object by the onboard means of the underwater vehicle of depths, taking into account the depth of submersion of the underwater vehicle in points of the matrix corresponding to the surface of the bottom section, above which the underwater vehicle was located with one of equal-size combinations of depth values measured when searching for an object, taking into account the depth of submersion of the underwater vehicle, on the same area at points of the matrix corresponding to the surface of the bottom in the search area.

EFFECT: enabling determination of the location of an underwater vehicle relative to the location of a search object in an underwater state without using hydroacoustic and orographic reference points.
