Determine Gyro Error and Compass Deviation by Sun's Amplitude 1: Using Amplitude Formula

This video provides a step-by-step guide for determining the Gyro Error and the deviation by the Sun's amplitude using the formula: Sin Amp = Sin Dec / Cos Lat.
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.
