Junior Navigation is the first of a two-part program of study in offshore (open coast) navigation. It is designed as a practical, how-to course using GPS for offshore navigation with sun sight taking using a sextant as a backup technique. The more advanced techniques for other celestial bodies and sights are for study in the subsequent Navigation Course. JN subject matter includes: basic concepts of celestial navigation; how to use the marinerís sextant to take sights of the sun; the importance and techniques of accurate time determination; use of the Nautical Almanac; how to reduce sights to establish lines of position (LOPs); and the use of GPS, special charts, plotting sheets and other navigational data for offshore positioning and passage planning.
Junior Navigation and (later) Navigation have been re-introduced as a two course (developed by our USPS partners) equivalent to Celestial Navigation . The first offering, JN, is a gentle introduction to use of the sextant to obtain sun sights to augment and validate electronic positions, and to extend the use of conventional navigation techniques as learned in Advanced Piloting. The course material includes: concepts of celestial navigation; use of the marinerís sextant to take sights of the sun; the why and how of accurate time determination; how to use the Nautical Almanac; sight reduction to determine lines of position (LOPs); special plotting sheets, charts, and other navigational data for passage planning and offshore positioning.
