Abstract

Access to the precision of the Stellar Reference System has to be improved for the coming years and decades. With new intermediate angle measurements (a few degrees), a dual-object IR interferometer can bring a decisive contribution to the Tycho Reference Catalogue. The instrument should be highly efficient, in terms of sensitivity and automatic star captation. Two possible beam combination schemes are discussed in this respect: a correlator interferometer and a Michelson stellar interferometer.
