摘　　要：为了提高恒温晶振频率的准确度和稳定度,设计了基于ZYNQ技术的GNSS驯服恒温晶振频标装置。在ZYNQ的PL端采用粗测量加细测量的方法测量时间,PS端使用奇异值剔除与滤波算法对测量数据进行处理,实现恒温晶振频率的驯服和时间跟踪。采用模块化设计和编程,提高了装置的通用性和可移植性。通过实验测试,对恒温晶振驯服前后的数据进行多次比对,结果表明其平均频率准确度达到1.09×10^(-12),频率稳定度达到8.56×10^(-12),其稳定度提升了两个数量级。In order to improve the accuracy and stability of Oven Controlled Crystal Oscillator(OCXO)frequency,GNSS tame OCXO frequcncy standard device based on ZYNQ technology is designed.In the PL end of ZYNQ,coarse measurement and fine measurement is used to measure the time,and the PS end uses the singular value elimination and filtering algorithm to process the measurement data to realize the taming and time tracking of the OCXO frequcncy.Modular design and programming arc adopted to improve the versality and portability of the device.The results show that the average frequcncy accuracy reaches 1.09×10^(-12) and the relative frequency stability rcaches 8.56×10^(-12),Its stability has improved by two orders of magnitude.
