What is Compass Error Determination Methods about?
This document discusses methods of determining compass error, including terrestrial and celestial observations. Terrestrial methods involve transit bearings, leading lights, and observations once alongside, but have difficulties with preparation, resources, weather conditions, and parallax error. Celestial methods use azimuth observations of the sun, moon, planets, and stars, or the amplitude method, but are impacted by refraction error and weather. Both methods require clear skies and stable conditions.
