Paper Abstract

The first application of stellar interferometry by Michelson was undertaken to make an angle measurement. Present and projected applications of the very precise angle measuring capabilities of modern interferometers include, in addition to stellar diameters: binary star orbits, parallaxes, positions, proper motions and the astrometric detection of extra-solar planets. A brief discussion of what has achieved and what can be achieved is given with emphasis on positional work leading to fundamental coordinate frames and motions within such frames.
