Abstract :
A study team, funded by the European Space Agency, is working on some scientific and technological aspects of a future astrometric space mission. In this framework, we are carrying out an experiment which aims at define the bounds to the performance of the metrology subsystem necessary to the sub-nanometric stabilization of stellar interferometers in space.
