磁罗经自差的智能测定和校正系统

Intellectual measurement and correction system for deviations of magnetic compass

利用计算机自动比较传感器输出的信号和基准航向信号,测定出罗经自差,并计算罗经自差系数,在显示器上显示船舶的磁航向.并提出船靠码头利用自差系数校正自差方法,最后计算出剩余自差.

This paper is about using computer to compare automatically the signal comeing from the sensor with the standard course signal,to measure the deviations of a magnetic compass and to calculates the coefficients, and then to display ship′s courses on the digital displayer. This paper else gives a method of correcting the deviations with the coefficients when the ship gets alongside the wharf.
