Abstract：A new way which can be used to forecast the clock error by the traditional quadratic polynomial model based on the scale of day, then the output values is interpolated by Lagrange interpolation polynomial to form the final forecasting results is proposed. The results show that the new method can significantly improve the accuracy of longterm satellite clock error prediction.
