以最大限度保持星载原子钟稳定性计算结果的准确、可靠性为目标,分析了原始数据采样间隔、非连续间断时间序列、无数据段、频率漂移等因素对原子钟稳定性计算结果的影响。利用GPS卫星精密钟差数据针对阿仑和哈达玛方差进行了影响量级分析,得出了有益的结论。
In this paper in order to furthest maintain the accuracy and reliability of calculated on-board atomic clocks stability,the impact of raw data sampling interval,non-continuous time series,no data segment,frequency drift and other factors on the calculated atomic clock stability are analyzed.Using GPS satellite precise clock offset data the affected magnitude of Allan and Hadamard variances are analyzed,and useful conclusions are given.
