DETERMINATION OF THE AZIMUTH WITH SOLAR OBSERVATIONS WITHOUT ANY PARTICULAR ASTRONOMICAL KNOWLEDGE AND SPHERICAL TRIGONOMETRY

摘要

Determination of astronomical Azimuth from a Fixed station A to a Trigonometrical point B, seen from A, constitutes a problem resolvable in different ways. If point B is not present, we can employ a geodetic TARGET to calculate astronomical azimuth from solar observations, and consider such azimuth as a geodetic azimuth. Using rectangular coordinates and non spherical trigonometry, the solution of the problem becomes a simple linear solution, with the employ of planes and straight lines on the space of celestial sphere.
