As ships and maritime transport have evolved, knowledge of navigation methods has also evolved, reaching today modern means that require less of the skills and time of navigators to determine the position of the ship on sees and oceans. However, the

Positioning with celestial bodies (celestial navigation) is the art of determining on the surface of the earth based on measurements of celestial bodies which have guided sailors for hundreds of years. Astronomical positioning methods or celestial bo

Finding one's geographical position (fix) without the use of a Global Navigation Satellite System (GNSS), which was common place before the establishment of the latter, could be tedious and/or inaccurate. Apart from sound knowledge of spherical trigo

The authors give a personal account of the use of astro navigation during the years before GPS became the primary aid for oceanic navigation. The paper also contains an account of the support provided by The Nautical Almanac (NA) together with its as

A direct method for obtaining the two possible positions derived from two sights using vector analysis instead of spherical trigonometry is presented. The geometry of the circle of equal altitude and of the two body fixes is analyzed, and the vector

What kinds of astronomical lab activities can high school and college astronomy students carry out easily in daytime? The most impressive is the determination of latitude and longitude from observations of the Sun. The “shooting of a noon sight”

Described is a simple method of observing and calculating longitude from lunar altitudes that does not require a succession of approximations. The method is unique in that the observations and calculations employed are standard procedure for practisi

This paper presents a simplified sight reduction method (ABHAV) which is easy to use and accurate to less than 1 arcmin in altitude without interpolation, limited only by the accuracy of the input data. It is intended to be used in place of the Modif
