为了寻求改进地方原子时算法的可能性,基于原子钟的离散动态模型,分析研究了Kalman滤波算法在地方原子时计算中的具体应用。采用中国科学院国家授时中心的18台铯原子钟数据,分别计算出基于ALGOS算法和经典Kalman算法的时间尺度。结果表明,两种时间尺度在性能方面极为相似,短期和长期频率稳定度相当。

英文摘要：

In order to seek for the possible way to improve the algorithm for local atomic time,the application of Kalman algorithm to atomic time is studied based on the discrete and dynamic model of atomic clocks.The time scales TA（ALGOS） and TA（Kalman） are calculated with ALGOS and Kalman algorithms respectively by adopting the data of the 18 cesium clocks operated at the National Time Service Center,Chinese Academy of Sciences.The results show that the performances of the two timescales are similar,i.e.,they are equivalent in short-term and long-term stabilities.
