Abstract：Based on the Hurst index characteristics of noise series, a new method determining the smoothing parameter for semi-parametric models is proposed in this paper: a binary search method based on the Hurst index. We apply it to analyze simulated and real GPS coordinate series, and the numerical results show the proposed method can effectively determine the smoothing parameter, and the seasonal signal of GPS coordinates time series can be completely separated by using the determined semi-parametric model.
