摘要
介绍电罗径测定方位角的基本原理,阐述海洋工程中电罗径校正的步骤和注意事项,给出计算公式。分析直接法对电罗径校准产生的误差,提出利用天文测量手段测量船舶方位角的最有利观测条件。
The basic working principle of gyro-compass is introduced,the steps of compass calibration and main items are illustrated,and the formula of calculation is given.Through analyzingthe errors of compass calibration due to di- rect way,the best way for azimuth measurements with time-angle method is proposed.
