摘 要罗经分为陀螺罗经（电罗经）和磁罗经，是船舶重要的导航仪器，尤其是陀螺罗经，航向准确度较高，所指示的航向一般会连接到雷达、电子海图等航海仪器中，是驾驶员较为依赖的航海仪器。但是，再精密的仪器也会存在误差，罗经差的大小，将会直接影响船舶航行的安全，所以需要驾驶员掌握测量罗经差的方法，对航向、方位进行必要的修正。本文将针对集装箱船“长冠轮”在大西洋航行时，利用天体对罗经差测量方法进行详细的阐述，通过实际的测量，来谈谈对于天测罗经差测量的心得体会，以及今后对于实际航海应用的理解与建议。关键词：测量方法、注意事项、建议与体会.IAbstractThe compass is divided into the gyro compass (the gyrocompass) and the magnetic compass. It is an important navigation instrument for the ship, especially the gyro compass. The heading accuracy is high. The indicated heading is generally connected to the navigation instruments such as radar and electronic chart. Marine instruments that drivers rely on. However, there will be errors in the precision instrument. The size of the compass difference will directly affect the safety of the ship's navigation. Therefore, the driver needs to master the method of measuring the compass difference and make necessary corrections to the heading and orientation. In this paper, we will use the celestial body to describe the compass difference measurement method in detail when the container ship "long crown wheel" sails in the Atlantic Ocean. Through actual measurement, we will talk about the experience of measuring the compass measurement of the sky and the actual navigation. Application understanding and recommendations.Key words: Measurement methods, precautions, suggestions and experience.IIIII目 录第 1 章 绪论................................................................................................................................11.1 研究背景...........................................
