Assumed Position in Celestial Navigation: Practical Guide and LOP Determination
This video shows how to determine the Assumed Position and its practical use in Celestial Navigation. It includes a brief discussion on how to use AP to determine LOP by celestial observation.
Assumed Position, AP, is a chosen or hypothetical position used primarily in celestial navigation when calculating a ship’s position based on observations of celestial bodies. It is typically not an actual or fixed location but a theoretical one chosen for ease of computation, often determined using the Marcq Saint-Hilaire method with the help of Sight Reduction Tables, Pub. No. 249.
