摘要
介绍了原子时的ALGOS算法、Kalman算法及小波分解算法的原理。分析了这 3种算法的特点 ,并比较了 3种算法计算的原子时的稳定度。实验结果表明 ,小波分解原子时在取样时间大于 15 0天的稳定度不比ALGOS算法和Kalman算法差的前提下 ,取样时间小于 15 0天的稳定度明显优于前两者。
The principles of ALGOS(BIMP) algorithm, Kalman algorithm and Wavelet Decomposition Algorithm(WDA) of atomic time are introduced. The characteristics of these three algorithms are analyzed and the stabilities of the time scales calculated with them are compared. The experiment results show that the stability of the atomic time scale calculated with WDA is apparently better than that calculated with ALGOS algorithm and Kalman algorithm when sampling time is less than 150 days when the former is not worse than others when the sampling time is more than 150 days.
