azimuth compass

Take celestial azimuth and find compass error on each watch if the weather is fine.

如天气好，每一班测取天体方位求出罗经差。

Electronic compass get the azimuth information of electropult, and the azimuth, distance and track of object will be displayed on EL display.

电子罗盘获取发射筒当前所指向的方位，显示屏显示目标的方位、距离、航迹和射击筒方位信息。

the correction of azimuth compass auto-aligning principle

方位罗经自对准原理的修正

the second is that the level circuit adopted by azimuth compass aligning circuit can only be two-order and can't be three-order, but as a matter of fact, three-order level circuit can be adopted in azimuth compass alignment.

方位罗经对准回路中，水平回路只能采用二阶调平回路，而不能采用三阶调平回路，而事实上采用三阶调平回路照样可以实现方位罗经自对准。

the reason why they are flaws and the more suitable statement about azimuth compass alignment are provided.

分析了原因，并给出了方位罗经对准原理更确切的描述。
