英文摘要：

We compare and analyze the SCB prediction results of fourteen BDS satellites based on the linear model, the quadratic polynomial model, the grey model （GM （1,1）） and Kalman filtering model, using precise SCB data of BDS to conduct the prediction tests. The SCB prediction performance of the BDS satellites according to corresponding orbit types is discussed and we summarize the characteristics of these models specific to the SCB prediction of BDS.
