摘　　要：利用频谱分析方法分析了卫星钟差的随机变化分量,得出了卫星钟差的随机变化分量具有一定周期性的结论。针对这种特性,提出了一种新的拟合方法。实践表明,这种新方法具有很高的插值和预报精度。A conclusion that the random variation component of satellite clock error has a certain periodicity by using spectrum analysis method to analyze the random variation component of satellite clock error is discussed. According to this characteristic, a new fitting method is proposed. It shows that the new method has high interpolation and prediction accuracy in practice.
