浅析用GPS校正磁罗经自差

A probe of how to correct magnetic compass autodyne by GPS

航海界通常采用爱利法来校正磁罗经自差。用GPS显示的航迹向COG来走主磁航向 ,然后用航向比对法来消除与测定磁罗经自差 ,这是一个新型的课题 ,并结合实际工作对该方法的可行性进行了分析。

The navigation circles usually use AiLi method to correct magnetic compass autodyne. This context introduces a new way to follow the subject magnetic course to COG by the track displayed by GPS,and then to eliminate and ascertain the course contrast method . This context also analyse its feasibility combined with practice.
