基于GPS锁定高稳晶体振荡器技术的研究

Research of Techniques to Lock High-stability Crystal Oscillators Based on GPS

对基于GPS锁定高稳晶体振荡器的技术要点进行了研究。设计了采用量化时延原理进行短时间间隔比相 ,对噪声数据进行卡尔曼滤波处理 ,以及系统的实现方式。

Some practical techniques to lock High-stability crystal oscillators based on GPS are given in the paper. Using quantized time delay method to compare a short time interval and a Kalman filtering algorithm to process noise ,the methods can complete a high precision.
