Scientific paper

In this paper, the important influence of the observations of the Hipparcos satellite on astronomy is described, meanwhile its short disadvantages are also pointed out: limited magnitude is only 12 mag and the accuracy of proper motions are not high enough. In the second part of this paper, the predictive objectives, observational arrangement and current progress of various ground based observational plans for expanding to faint stars, such as TAC, SDSS, UCAC-S, POSS, are introduced. In the third section, some space astrometric projects, which will probably be carried on in the next decade, such as GAIA of ESA, SIM of US JPL, DIVA of Germany, FAME of US Naval Observatory and STRUVE of Pulkovo, Russia are described. In the last section, the applications of sub-milliarcsecond astrometric data on astrophysics are mentioned.
