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. #celestialnavigation #navigation #maritime #seafarer #seaman #bsmt https://youtu.be/5uNJRmP7U6k
