Abstract. A technique is presented that can be used to identify the error of prediction of divergence of time scales discordance for space-distributed clocks. The proposed approach accounts for the error of com-paring the time scales of remote clocks as well as nonstationary properties of the time scale generation process dependent on the master clock generator parameters. The approach makes it possible to gene-ralize the numerical solution obtained for the problem of prediction the time scales divergence error to a wide range of master clock generators. A mathematical model of the clock generation process for the generator under consideration is proposed. The model adequacy is demonstrated using simulation experiment and comparison with the results of measurements performed with the real generator. A method and algorithm of calculating the error of time scales divergence prediction are described, results of a test problem solution with the method are presented.
Keywords: mutual synchronization, prediction error, time scales divergence
