摘要
阐述了如何利用 GPS对单个计算机进行精确授时。系统利用软件 ,从 GPS接收器获取 UTC时间码和秒定时信息 ,并对计算机时钟进行校准。该系统具有投资省、精度高、用途广等特点 ,取得了满意的效果。
A system synchronize the time of a single computer to UTC accurately by GPS is introdueed.The system receives UTC timestamp and PPS from GPS using software, then calibrates the clock of computer. The system has some characteristics such as low investment, high precision and wide-range use.
