The test bench for testing and calibrating the measuring geodetic instruments for flat angle measurements has been created at Vilnius Gediminas Technical University, Institute of Geodesy. This test rig incorporates multiple-angular position determination principles – photoelectric angular encoder, polygon-autocollimator and circular-scale-microscope. Such a diversity of implemented methods allows cross-calibration and testing each principle using the other one. Similarly, there may be multiple methods of testing and cross-calibration used. The covariation and correlation analysis of the measurement data are received and analysed.
