摘要
介绍了GPS系统的组成、GPS的信号结构、GPS的授时的基本原理,并给出了GPS应用系统的设计方法和具体的同步程序框图及硬件结构框图.该系统应用于数字地震记录仪等测量系统中,提高了测量系统的时间服务精度,其时间同步精度可达1μs,为地震观测提供了理论依据
The composition, signal structure and principle of the time giving of GPS are described in detail and the design method of real time on line time giving system with GPS and specific synchronous program and hardware chart are introduced as well. By applying GPS to digital earthquake recorder, the accuracy of synchronization is up to 1μs, and this improves the measuring system′s time serving accuracy, and gives valuable data for the earthquake recorder system.
