STUDY ON AUTOMIC PREDICTION OF TIME BASED ON INTERPOLATION MODEL WITH TCHEBYTCHEV POLYNOMIAIS
利用切比雪夫多项式模型进行时间预报的研究

Two basic models,general polynomial model and Tchebytchev polynomials model which are used to predict the time deviation of atomic clock,are discussed.One day's clock bias of three different GPS satellite's clocks,which are launched in different period,are predicted by using of the precise clock bias data supplied by IGS,and the prediction results of clock bias are analyzed and compared,and the results show that when using the Interpolation model with Tchebytchev polynomials to predict the time deviation of...
