Astromeetria põhiülesanne on määrata võimalikult täpselt kindlaks, milline on mingil ajahetkel mingi taevakeha asukoht taevasfääril, ja kirjeldada selle kaudu taevakehade liikumist.
The field of astrometry, the precise measurement of the positions, distances and motions of astronomical objects, has been revolutionized in recent years. As we enter the high-precision era, it will play an increasingly important role in all areas of astronomy, astrophysics and cosmology.
