| Research Abstract |
The aim of this cooperative research was to unite the Terrestrial, Dynamical, Stellar and Extragalactic reference frames together into a unique conventional celestial reference frame. The unique celestial reference frame thus established would be most appropriate for analyzing the kinematics of optical and radio objects in a consistent fashion. The individual researches for this aim were as follows :
1) The extension of the optical fundamental reference frame FK5 to the fainter magnitude.
2) The establishment of a global radio reference frame with high accuracy.
3) The determination of the earth orientations under the international cooperation with VLBI networks.
4) The re-construction of a basic theory of the celestial reference system for high precision observations.
5) The future projects for constructing astrometric instruments on the ground and in the space.
6) The galactic astronomy based on the modern kinematic data of stars.
The results achieved by the individual members of this Research have been published in the Proceedings of Symposiums, edited by M.MIYAMOTO, "Linkage of Terrestrial, Dynamical, Stellar, and Extragalactic Reference Frames (I)-(III)" and "The Astrometry and the Galactic Astronomy."
