Abstract
A positional accuracy of 1.5 arcsec rms at the epoch of observation was required for the stars proposed for observation by the Hipparcos satellite. How this was achieved by collecting and investigating already available positions and proper motions in a special compilation catalog, carrying out new ground-based measurements, and a detailed analysis in combination with new observations of double and multiple stars is described in this paper. Special emphasis is put on how to achieve a link of the resulting Hipparcos catalog to an inertial system.
