We present a research of the time evolution of the redshift of light receivedfrom the binary star that moves in the external gravitational field of Kerrblack hole. We formulate a method for the solution of inverse problem:calculating of the parameters of relative motion of stars in binary systemusing the redshift data. The considered formalism has no restrictions on thecharacter of the motion of the center of mass of a compact binary star and canbe applied even in the case of binary motion close to the event horizon of asupermassive black hole. The efficiency of the method is illustrated on anumerical model with plausible parameters for the binary systems and for thesupermassive black hole, which is located in the center of our Galaxy.
