小型船舶磁罗经自差智能校正系统的设计与实现

Design of the System for Automatically Rectifying Magnetic Compass Deviation for Small-scale Ships

针对未安装电罗经的小型船舶,提出一种磁罗经自差校正方法,研制磁罗经自差测量及校正系统,通过观测已知位置的物标自动测量任意航向上的罗经自差,采用高斯消元法计算出准确自差系数,逐一消除船舶自差。

A new method of rectifying magnetic compass deviation for small-scale ship without gyrocompass , and a system was developed for automatically measuring and rectifying magnetic compass deviation .The system can automatically measure de-viation by observing the known position object , calculate deviation coefficients by Gaussian elimination , and rectify the deviation by these coefficients one by one .
