About

FM 6-300 Section I. INTRODUCTION 1. Purpose and Scope a. This manual is a compilation of tables and charts for use in computing astronomical azimuths for the field artillery. These tables and charts are used for computing azimuth of the sun or selected stars by either the altitude or hour-angle method. A special table (table 12), which is a tabular method of computing Polaris, is included for a rapid computation of a Polaris azimuth. The secant tables accompanying table 12 are permanent; however, the example portion of the explanatory part of the table will be updated annually. Tables and charts are also included to correct astronomic azimuth to grid azimuth, to extend azimuth by simultaneous observation, and to perform zone- to-zone transformation of azimuth. b. Data contained in tables 2, 10a, 106, 1.1, and 12 are current only for the year in which the manual is effective.
