| Abstract: | The methods currently used in satellite clock error forecasting are quadratic polynomial model and grey model.The shortcomings of these models are discussed,and a new ARIMA(0,2,q)model is proposed to model and predict the clock error for one day.The analysis of the time series of satellite clock error reveals that the related character of clock error accords with that of moving average model(MA)after differentiation two times.Thus the ARIMA(0,2,q)forecasting model is established.The final results by use of ... |
