Paper Abstract

Principles of automatic two-coordinate stand building are discussed. A base of using the stand is direct frequentative high-accuracy measurements of fixed angles for various zenith directions. Results of these measurements are introduced into special microprocessor for composing system of simultaneous error equations. The solution of the system makes it possible for setting both general instrumental errors of horizontal and vertical angular measurements and separate components of these errors. The system of base directions is set by two-coordinate photoelectric autocollimators aiming to special prism standard. The standard is certified beforehand and used then periodically for verification of the spatial stability of the stand. Analysis of an accuracy has illustrated that the error of certification may be not exceeded by 0,3 angular second for frequentative measurements if the error of the autocollimators are less to 0,1 angular second.
