摘　　要：介绍了陀螺罗经、平台罗经和惯导等常见船载导航系统,分析了导航系统向伺服系统提供航向和横、纵摇等姿态信息的情况。阐述了船载伺服系统为实现姿态稳定对导航系统相关信号的需求和误差对伺服系统的影响。论述了航向信号接收的相关转换器选型技术要求和特殊转值过零的软件处理流程。给出了为了实现三轴指向稳定而将将船体姿态信号进行坐标变换的一种简单推导过程。The article introduces some common shipborne navigation systems,such as gyrocompass,platform compass and the inertial navigation system,and analyses the information on ship attitudes provided by the navigation system to the servo system,such as ship course,rolling and pitching.It also describes the navigation signal requirements of servo system for attitude stabilization,as well as the influence of the precision on the servo system.How to select the converter chip and how to implement program processing is another subject.At last,the article provides a simple formula on coordinate transformation for ship attitude signals to realize three-axis stabilization.
