A global space astrometry mission, Gaia is building the largest, most precise three-dimensional map of our Galaxy by surveying nearly two billion objects.

The limitation imposed by long term irregularities in the earths atmosphere is estimated to be on the order of 0.01 arcsec. We have no control over the nature, content and availability of those sites. The present inter- ferometric measurements are thought to be dominated by instrumental errors, indicating that a significant improvement is possible in the precision of astrometric measurements.
