Book Description
Star catalogues are important tools for the geodesist in the determination of astronomic position and azimuth. Fundamental general catalogues contain the most accurate stellar positions and proper motions. Like other users, the geodesist depends on astrometrists for the discussion and development of fundamental general catalogues. The internationally accepted FK4 is the best contemporary fundamental general catalogue. An expanded and improved revision, the FK5, is planned for completion by 1980. Because of increasing accuracy requirements for astronomic position and azimuth, it is desirable that the geodesist be aware of uncertainties contained within catalogues. The general development of star catalogues is included as background information. (Author).

Book Description
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.
