对观测天体罗方位误差的分析

A Study of Compass Azimuth Errors in Observing the Celestial Bodies

在观测天体罗方位求罗经差时,天测罗方位的误差是一个不可忽略的因素。此文对方位圈或罗盘倾斜所产生的天体罗方位误差进行分析,希望对航海人员在学习和应用中有一定的裨益。

In the process of calculation and measuring, the affects of the errors in measuring the celestial body＇s bearing on the precision of the compass error cannot be neglected. This article studies the errors of the celestial body＇s compass bearing which are produced by the compass azimuth circle and the compass tilt ,and puts forward new views. Hopefully, this study will bring certain benefits to colleagues and navigators in studying and applying it.
