Herasymenko K. Information technology for suppressing interference with satellite radionavigation based on adaptive spatial filtering.

The paper formulates and solves the actual scientific task of improving the methods of ensuring the reliability of information of satellite information systems based on the compensation of errors in the data exchange paths. The method of determination of complex weight coefficients of adaptive spatial filtration is developed, the distinctive feature of which is the use of the Quasi-Newtonian method for finding the minimum of the target function - the method of conjugate gradients and the experimentally confirmed procedure of adjustment to the conditions of specific errors. The method for compensating errors in the data exchange paths, which consistently uses the phase of spatial error filtering, and the phase filtering phase, has been improved. The method of processing information is improved to ensure its reliability in the conditions of error in the data exchange paths on the basis of adaptive spatial error filtering. The application of the proposed methods allows to provide compensation for errors in the data exchange paths to three sources of errors with allowable computing costs and to use in existing satellite information systems.
