用于船舶罗经校正的太阳方位角EXCEL计算软件编制

Simplified Calculation of Solar Azimuth for Ship Compass Calibration

本文介绍了船舶罗经校正传统的太阳方位计算法所产生误差编制了太阳方位角计算的EXCEL软件,实现了只需要输入五个关于时间和船所在经纬度的数值即可得到准确的太阳方位角值,从而达到减少太阳方位角的计算时间、提高准确率、减小误差的目的。

This paper introduces the error produced by the traditional solar azimuth calculation method of the ship,"which compiles the EXCEL software for the calculation of the sun's azimuth,and realizes that only five values of the time and latitude of the ship can be obtained to obtain accurate sun azimuth values,thus achieving the purpose of reducing the calculation time of the sun's azimus,improving accuracy and reducing the error.
