Description and use of the Telemeter, Horary, and Sine Quadrant. Abridged digital edition of the fifth edition.
The fundamental concepts of distance and altitude calculations, as well as advanced tutorials, formulas, and reference tables.
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 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.
This 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.
Using a Wndsn Quadrant Telemeter to determine latitude (at night with Polaris), calculate declination of the day with the respective arc, and a measurement of the Sun altitude (backsighting), one can derive at least 18 data points and actually calculate all of them directly on the quadrant.
