The fundamental concepts of distance and altitude calculation, as well as advanced tutorials and formulas. Mastering time and date and predicting the apparent movement of the Sun and the stars. Includes a primer on the basics of astronomical coordinate systems and the navigational triangle. 5th, once again expanded and revised edition.
The Wndsn Quadrant Telemeter is a simple observational tool for measuring angles via various inputs combined with a number of means to directly process the acquired values. This instrument is equally useful in altimetry, surveying, etc., for taking altitudes, and determining right-angled triangles. This manual is about the theory and practice of the instrument.
The 5th edition expands upon the 3rd and 4th edition, now clocking in at 538 pages, 197 figures, 31 tables, 50 equations, 139 glossary entries, and 97 bibliography entries.
