The methods of astronomical definitions of the geographic coordinates of the point and the azimuth of the direction are based on measuring the horizontal coordinates of the luminaries at fixed times of a particular time counting system. The programs of the methods introduced into production are designed for the most favorable conditions for observations of luminaries, when the influence on the result of the measurement errors and the coordinates of the point is minimal. When determining the influence of errors in the equatorial coordinates of light, the conditions of observation are not always the most advantageous. However, these errors, in particular random errors, are negligibly small in comparison with measurement errors.
