基于GPS时间源的自控时钟的设计与实现

分析了普通石英大钟时间源和控制方式技术上的不足,提出了以GPS为时间源,采用角度定位闭环控制的高精度自控时钟的设计思路。重点叙述了GPS信息格式和筛取时间信息的方法以及使用旋转变压器作角度定位的原理和实现方法。

Design and Implementation of Self-Control Clock Based on GPS Time Source

The paper analysed the shortage of normal crystal clock on the time source and control method ;brought forward a design of high precision self-control clock with the close loop control on angle orientation ,based on GPS time source.It emphasized the GPS information format ,approach to picking up the time information ,and also the principle and implementation for angle orientation us-ing rotating transformer.
