摘要

研究了gps计时中局部晶体钟的时间间隔误差(TIE)模型的最佳时间步长(采样间隔)。对于接收机的锯齿噪声,采用无偏有限脉冲响应(FIR)滤波算法估计局部时钟状态。我们利用嵌入到斯坦福频率计数器SR620的本地晶体时钟。测量使用SynPaQ III GPS传感器作为定时接收器,铷时钟(SR625)作为晶体时钟的参考时间源

Investigation of an Optimum Sampling Interval for a Local Clock TIE Model with an Unbiased FIR Filtering Algorithm
An investigation of the optimal time step (sampling interval) is provided for the time interval error (TIE) model of a local crystal clock in GPS-based timekeeping. For the sawtooth noise of a receiver, the local clock states are estimated employing an unbiased finite impulse response (FIR) filtering algorithm. We exploit the local crystal clock imbedded to the Stanford Frequency Counter SR620. The measurements are provided using the SynPaQ III GPS Sensor as a timing receiver and rubidium clock (SR625) as a reference source of time for the crystal clock
