Astronavigation From Square One

This new 2010 edition, published in October 2009, is an updated text originally published in the first edition using 2009 data. It is also available in e-book form. The paperback, comprising 289 pages, aims to address the varying "astro" knowledge base by informing those new to the subject with a straight-forward aid to understanding. It puts flesh on the bones of "astro" enabling the student to get so much more from a theory course. For the more experienced it offers some scientific detail and discussion of the astro-navigator's world. In short - learn astro NOT BY ROTE BUT BY UNDERSTANDING. It uses current data: - 2010 Sun, Moon, planet and star data - working in the present and near future rather than the misty past. The Nautical Almanac and its contents arte dissected in detail. There are 160, easily reproducible line diagrams to aid understanding and an extensive and detailed "astro" glossary. The sextant's development and use are explained. Time is explored in full - demystifying apparent and mean time. Straight-forward proformas are shown for each heavenly body. There are 40 fully worked examples, showing all the working. A new classification of the available tables is given, aiding their understanding and usefulness. Several data sources are explored- e.g. NP 314, NP 303, NP 401 and Reeds Astro Navigation Tables. Explanations and examples of ABC tables and formulae for azimuth computation are given. The use of a star-finder and the standard planet table are explained. Interpolation is discussed and its limitations detailed. Long-hand and calculator methods are shown in full detail, together with rapid sight reduction table methods. An appendix is dedicated to the understanding of the maths of spherical trigonometry. A full and detailed index is presented to aid in rapid reference.
