: The point on the Earth’s surface directly beneath a celestial body at a given moment, defined by its Declination (latitude) and Greenwich Hour Angle (longitude).

: A spherical triangle formed by the observer's assumed position (AP), the geographic position (GP) of the celestial body, and the elevated pole. Solving this triangle using trigonometry or tables provides a position fix. 2.

"Navigation and Nautical Astronomy" encompasses the traditional and modern methods mariners use to determine a vessel's position, course, and distance at sea. While modern technology like and GNSS provide high-precision automated fixes, the field is fundamentally grounded in Nautical Astronomy , which uses celestial bodies as "lighthouses in the sky" for independent position verification. 1. Core Principles of Nautical Astronomy : The point on the Earth’s surface directly

Nautical astronomy deals with the coordinates and motions of celestial bodies (Sun, Moon, planets, and stars) to find a location on Earth. Navigation and Nautical Astronomy
