Abstract
The paper describes the envisaged positioning and drive system for telescopes of the 2m class, gives some basic analysis for power consumption and positioning performance and proposes next steps for verification of the concept. A possible application could be in optical stellar interferometry where an additional delay could be spared if the positioning performance is better than 10nm. Fast re-positioning of the telescopes should allow for multiple baselines during one observing night giving the opportunity to obtain high spatial stellar images with high time resolution.
