GPS授时服务系统在气象业务中的应用

GPS Time Service for Meteorology Application

介绍了利用GPS的时间信息组建内部局域网的授时服务系统的方法:首先通过微控制器(MCU)将GPS接收器送出的二进制信息转换成各种不同的格式输出供服务器调用,然后通过基于网络时间协议的服务器/客户端时间校对软件,实现内部局域网计算机的自动对时。此外,针对GPS失锁或出现异常不可用的情况,提出了系统应对处理方法。

This article introduces the method of making time services based on GPS. First, it exchanges the binary information received from GPS receiver by MCU into various formats, thus the time service can use. Then, it realizes the automatic time service for LAN by the program of C/S time service based on NTP. In addition it provides the solutions when the GPS is unlocked or abnormity.
