The construction and accuracy analysis of the multireference equipment for calibration of angle measuring instruments

Abstract

Precise geodetic instruments are very widely used in geodesy, surveying, machine engineering, etc. Testing and calibration of these instruments is quite complicated task, although it is evidently needed. In this paper we present the creation and research of accuracy of the multireference (incorporating photoelectrical angular encoder, polygon/autocollimator and the circular scale/microscope(s)) test bench designed to perform the testing and calibration of such geodetic instruments.
