Research on Frequency Drift Correction Method of Spaceborne Rubidium Atomic Clock

摘要: 针对星载铷钟具有短期频率稳定度高和频率漂移大的特点，为更好地发挥其在导航卫星中的作用，通过分析具体的星载铷钟频率变化过程，研究了频率漂移修正的方法和策略，提出采用星载铯钟作为参考源进行频率漂移修正的途径。

Abstract: With the characteristics of high short term stability and large frequency drift,Rubidium atomic clock on board navigation satellite need to be compensated and corrected from time to time to highlight its advantage.According to its real trend of frequency drift after power on,different prediction methods were compared.The compensation technical route were proposed for autonomous navigation based on cesium and rubidium assembly.
