摘　　要：铷原子频标一般被人造地球卫星的发射系统、运载火箭导航、无线通信、电视转播、全球定位等系统用作频率标准和时间标准。频率准确度表示输出频率偏离标称值的程度,是衡量铷原子频标的重要指标之一,其精度直接影响用户设备的精度。目前铷原子频标输出的频率准确度指标可以达到优于1.0×10;的量级。文章通过对铷原子频标工作原理、校频原理的分析,比对了目前铷原子频标两种校频模式的优缺点,并提出了校频模式改进方式。The Rubidium atomic frequency standard is generally used as the frequency standard and time standard by the artificial earth satellite launch system,carrier vehicle navigation,wireless communication,TV broadcasting,global positioning and other systems.Frequency accuracy indicates the degree to which the output frequency deviates from the nominal value,one of the important indicators of the rubidium atomic frequency standard,whose accuracy directly affects the accuracy of the user’s equipment.The current frequency accuracy index of the rubidium atomic frequency scale output can reach an order better than 1.0×10;.Through the analysis of the operation and calibration principle of rubidium atoms,the two advantages and disadvantages of rubidium atoms are compared,and then the improvement mode is proposed.
