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

We propose a new control scheme based on analyzing the problems existed in the original machine tool. We use single chip Microcomputer as controller, stepper motor to drive machine table, and power monitor for grinding contact detecting. The principle of grinding contact detection was elaborated, the structure of computer hardware and software are presented. The developed control system has been used for machine. The results show that the control system runs properly and achieves the desired effect.

To test the accuracy of image motion compensation of space camera, the moving target simulator was developed according to the principle of relative motion. As the core controller, PIC microcontroller controls DC motor to drive photoetching turntable rotating to simulate the relative linear velocity between ground target and aircraft, and the rotation motion is divided into uniform velocity rotation and sinusoidal velocity rotation. Furthermore, the simulation of drift angle of aircraft was realized by controlling stepper motor to drive the photoetching turntable deflecting, and the deflection includes uniform deflection, sinusoidal velocity deflection and specified angle positioning. The design of the hardware and software of control system has been completed and tested, and the experiment results show that the control system has high control precision and meets the design requirements.
