Abstract:

Aiming at the limitation of forecasting the satellite clocks bias by using a single model, three methods of weighting the single model forecasting results are proposed. Namely, the classical weighted combination method, the forecast validity weighting method and the average weighted combination method, and these weighted combination method are used in the middle and longterm prediction of the satellite clocks bias. At the same time, the prediction results of the three combined models are compared with those predicted by the single model and the advantages and disadvantages of the three weighted combination models are analyzed.

Key words:satellite clocks bias (SCB); linear polynomial (LP); quadratic polynomial (QP); grey model (GM); combined model
