Design and Implementation of the High Accuracy Frequency Steering System Based on TDC

介绍GPS驯服晶振的原理；采用高精度时间间隔测量芯片TDC测量时间间隔；设计了一种Kalman滤波算法对测量数据进行实时滤波，并通过实验对系统进行了验证。

This paper introduces the principle of steering crystal oscillator with GPS signal. It uses a high resolution time interval measurement chip of TDC to measure time interval. A Kalman filtering algorithm has been designed to filter the measured data in real time and verify the system feasibility through experiments.
