Celestial fundamental catalogues are a prerequisite for the
determination of absolute positions and motions in space.
Presently, positional astrometry is at the watershed between
classical fundamental catalogues, based on moving reference stars,
and modern catalogues, based on extragalactic reference objects
with non-measurable motion. This book addresses the concepts and
methods of the respective construction techniques leading to the
stellar frame of the FK5 (fifth fundamental catalogue) and to the
newly adopted extragalactic radio reference frame, ICRF
(international celestial reference frame), with its extension to
optical wavelengths by the Hipparcos Catalogue. While principal
outlines of meridian circle observations are given, emphasis is put
in some detail on the VLBI technique as applied to astrometry, and
to the observational techniques used in the Hipparcos mission,
including the tie of the originally non-anchored rigid Hipparcos
sphere into the ICRF.
