| Abstract: | The quadratic polynomial model and grey model used in short and long period clock errors predictions are analyzed, considering that these models only think about trend item but not random item. An improved method is given,which combines wavelet and ARMA. The computation results show that through an example by using the precise clock errors from IGS (International GPS Service) the improved model has higher accuracy. |
