Method of Relative Measurements to Control the Accuracy Characteristics of an Automatic Astronomic Azimuth System

摘要

A method of relative measurements to control the accuracy characteristics of the automatic system for determining the astronomical azimuth is proposed and the algorithms for its implementation are given. The development of the method is relevant since there is no reference base for direct (absolute) control of accuracy characteristics by intercomparison. The method of relative measurements consists in estimating increments (changes) in the values of the astronomic azimuth of the sighting axis and the control element under controlled forced changes in the intermediate parameters of the system. Special algorithms have been developed to estimate the expected increments of astronomical azimuth values.
