Determine Gyro Error and Compass Deviation by Sun's Amplitude: A Step by Step Guide

This video provides a step-by-step guide to determining the Gyro Error and the deviation using the Sun’s amplitude, based on the formula: Sin Amp = Sin Dec / Cos Lat. It demonstrates two methods for finding the deviation when variation is applied to the total error.

Additionally, the video corrects an error from Parts 1 and 2 regarding the proper naming of the Sun’s amplitude suffix.

Amplitude refers to the angular distance of a celestial body (such as the Sun or Moon) measured along the horizon—from the East point when the body is rising, or from the West point when it is setting.
