利用授时型接收机的秒信号驯服原子钟，可以提高原子钟的长期稳定度。由于接收机受各种噪声的影响将导致得到的铷钟相对于星钟频差数据不精确。本文设计了一种应用于校频系统的卡尔曼滤波算法，卡尔曼并采用FPGA内嵌ARM处理器对算法进行了验证，多次采样的数据滤波处理得到了满足要求的频差数据，为校准铷原子钟创造了条件提供依据。

The long stability of atomic clock can be improved by using the second signal of timing receiver to tame the atomic clock. The frequency difference data of rubidium clock is imprecision caused by the various noise influences on the receivers, so a Kalman filter algorithm applied to the frequency calibration system is designed in this article. This algorithm is validated by using FPGA embedded ARM processor. According to the data filter processing, the satisfied frequency difference is gained to calibrate the rubidium atomic clocks.
