摘　　要：捷联式惯性导航系统是一种先进的自主式导航系统,它能以较低的成本得到较高精度的姿态和位置信息,因此近年来受到了世界各国导航界的重视。本文就船用捷联式惯导系统的数据采集进行了分析与探讨。文中首先论述了惯性仪表的数据采集方法,然后针对船用捷联惯导系统的特点,设计了一个船用捷联惯导系统的惯性仪表数据采集电路,并对其数据采集、同步和中断等部分作了较详细的分析。The strapdown inertial navigation system is a kind of advanced autonomous navigation systems which can supply attitude and position signals of higher accuracy with a lower cost than other system.Specialists in the navigation-aid field in many countries have been paying attentions to it recently. In this paper,the data sampling methods of the inertial elements are discussed,a data sampling circuit for the inertial elements of marine strapdown inertial navigation system is presented and the data sampling,sync.ro and interrupting operations are described in detail.
