leeway angle

基本解释

According to the obvious difference of yaw-bias in different voyage calibrations, the result of analysis shows that the leeway and drift angle is the primary reason.
针对目前多波束艏摇偏差参数不同航次校准其结果相差很大的问题，分析得出了风流压差是产生此差值的主要原因。
To ensure the vessel voyage along the predetermined course, the rudder angle should be changed reasonably at the right moment according to the various leeway circumstances.
为使船舶沿预定的航向航行，应根据船舶偏离航向的情况适时合理地改变舵角以修正航向。
On the basis of establishing the leeway motion model, the laws of the motion are studied and the strategy on ship off-course correction is discussed by using reasonable rudder angle timely.
在建立船舶偏航运动模型的基础上，对偏航运动规律进行分析，提出适时合理地采用舵角进行偏航控制的策略。
