Abstract

The value of time synchronization between Rubidium clock and GPS clock, which changing with time, was studied by using the time series prediction method. Some issues such as the selection of the smoothing coefficient and the prediction accuracy problem of linear exponential smoothing, secondary exponential smoothing and cubic exponential smoothing were discussed in this paper. The results showed that the mean absolute error of prediction was minimum if smoothing coefficient equaled to 0.5, and the result of cubic exponential smoothing prediction coincided preferably to the measure values.
