Article Preview

The main task of this research was improvement of precision of positioning drive, installed in a test rig for testing and calibration of the geodetic instruments at Institute of Geodesy of Vilnius Gediminas Technical University. Replacement of a stepper motor and a microstepping controller design increased positioning accuracy up to 0.1. Vibrations and noise of the test rig were significantly reduced using an optimized control algorithm, where resonating step frequencies were bypassed. Time of scale rotation between measurements (every 30) reached less than 1.5 min. Methods for further precision improvement were evaluated and this research is currently in progress.
