National Astronomical Observatory, Japan has a plan to construct a new VLBI system named VERA (VLBI Exploration of Radio Astrometry). The system can measure precise positions of Galactic radio sources (H2O masers and SiO masers) referring to adjacent radio sources (QSO etc.) by using a differential VLBI method (Sasao and Morimoto, 1991).
