Modeling of algorithms of operation of the magnetometric facility location refinement system

Problem statement. Currently, many algorithms and functionalities for the implementation of correlation-extremal systems from which it is necessary to select the optimal ones for constructing a magnetometric position correction system. The purpose of this work is to coputer modeling and study mathematical models «without search» and «search» algorithms of the magnetometric facility location refinement system of an object based on real data on distribution of the abnormal magnetic field component of the earth in order to select the optimalalgorithm for subsequent application The results. It has been shwown that ehe beat results in terms of the errjr in refining the position of an aircraft using a magnetometric system are provided by modified search algorithms based on the sum of the squares of the deviations of the measured by the magnetimetric sensors from the reference data and the Person correlation coefficient. Practical significance. The selected algorithms can be used tj creste a msgnetometric system for correcting the locetin of an object.
