Abstract.

The goal of this research is the examination of results of the work of algorithm for positioning of vessels across the depths of the seabed based on the clusterization of the initial digital seabed map. The classical methods of positioning in the marine navigation systems are based on comparison of the map of the depths and measurements using onboard depth sensors. Unlike the classical search algorithms the proposed algorithm uses depth clusters as the map, and executes the search of the most likely points of vessel location based on clusterization of data. The methods of this research is the classical theory of correlation-extreme systems alongside the modern theory of cluster analysis. The initial data were acquired in the result of pilot experiments. The computer model allows visually displaying the results of the work of algorithm. Graphic information in combination with the numerical parameters of the work allows carrying out the analysis of results, as well as visually and analytically assess the efficiency of the developed algorithm. The work contains the detailed images of graphic information, clusterization of the initial data, and stage process of clarification of coordinates of the vessel. The results of this research represent the new contribution into the theory of algorithms of the navigation systems across geophysical fields. The conducted research along with the results of calculation demonstrated the efficiency of application of the cluster analysis in navigation systems across the depths of the seabed.

Keywords: depth , correlation-extreme systems, bathymetry, criterion function, metrics, navigation systems, clustering, seabed, accuracy , digital terrain model
