Grimoire Quadrantis Telemetrum
Quadrant Telemeter Official Manual
The Wndsn Quadrant Telemeter manual provides the description and describes the use of the Telemeter, Horary, and Sine Quadrant.
The 5th edition of the manual describes and teaches the operating system of the Quadrant Telemeter and once again refines and expands the knowledge base and power of the Wndsn suite of telemetry tools. Now available, the 5th edition features a number of entirely new sections, among which -- for the first time -- tutorials written by community members, and it presents some original research results on the functions of the Sine Quadrant.
The 5th edition, advances its function as a study guide and textbook both for the novice and expert user with an entirely new part laying out and codifying standard situations for applied trigonometry in the field, with worked examples for the various ways of both sighting and processing the acquired data.
The Wndsn community has enthusiastically embraced the tutorials from the 3rd and 4th edition and came up with a number of new ways of using the Quadrant Telemeter -- from using the Telemeter without any known dimensions to getting into the intricacies of Sun calculations, all the way to employing the Quadrant as a star compass, using both its sighting and its computing capabilities for night time navigation.
The hidden jewel of the 5th edition is the part on the Sine Quadrant, an ancient tool that looks like graph paper. It has been established before that the Sine Quadrant is a fully functional (super) computer for all things trigonometry and astronomy. Previous editions of the Grimoire presented the contemporary state of research in literature while trying to make it accessible with working examples. Some of that research and the resulting methods have been unsatisfying and some techniques have been hard to replicate. Wndsn invested a lot of time and custom-made graph paper in original research to solve the remaining issues and re-discover lost functions and methods to be now able to present the full set of instructions for the Sine Quadrant, an ode to this unique instrument and its inventors more than a millennium ago.
The manual still and fundamentally covers the concepts of distance, height, and altitude calculations together with a concise primer on the basics of practical astronomy and its terms and relations as needed for the mastery of time and space, from the moving parts of date and time to the intricacies of hour angles and right ascension.
The 5th edition expands upon the 3rd and 4th edition, now clocking in at 538 pages, with 197 figures, 31 tables, 50 equations, 139 glossary terms, as well as 97 bibliography entries.
The changes to the 5th edition in numbers: 140 additional pages, 68 new figures, 9 new tables, 10 new equations, 20 new bibliography entries, and 26 new glossary terms.
An abridged version of the 5th edition is available as a free download with every Telemeter. At about 300 pages, it is pared down to just setup instructions and tutorials. A hardcover, as well as a German edition is also available.
The official Wndsn Quadrant Telemeter manual. The cover design pays homage to medieval mathematical and astronomical books; the styling of the title as a "Grimoire" is a play on textbooks of magic with instructions on how to make spells, talismans, and the like, "Grimoire Quadrantis Telemetrum" -- Textbook of the magic of Quadrants and Telemeters. Finally; the author's name at the top; "Filiusventi" is a hint at the practice of Renaissance scientists to latinize their names; venti is wind, and filius the son.
