GPS接收机的Y2k问题和WNRO问题将导致GPS时间系统的混乱,由此引发GPS接收机硬件、软件故障,从而使与此相关的一切GPS数据(包括定位、导航、授时)都将产生混乱、错误甚至系统崩溃。问题隐蔽较深、危害很大。因此,所有GPS用户都在关注这一问题的由来、危害、表现形式和解决办法。本文就Y2k问题和WNRO问题做简要论述,以飨对这一问题感兴趣的业内人士。

The appearance of Y2k and WNRO of GPS receiver may cause confusion of GPS timing system, as a result that hardware and software will be failure. Then all the GPS data related with positioning, naviga-tion and timing will be confused ,even the whole system may break down. If we do not care about these problems, the damage will be more serious. Now all of GPS users not only pay close attention to the cause, damage and forms of these problems but also concern more about its resolution. The author of this paper made a further study on this hot topic and gave some suggestions.
