Scientific paper

The astrometric parameter determination, as adopted by the FAST (fundamental astronomy by space techniques) consortium, for the Hipparcos satellite data reduction, is presented. The objective is the improvement of the approximate positions, proper motion and parallaxes of the program stars provided in the input catalog. The results for single stars on reference great circles accumulated throughout the mission, are discussed. The attempt to derive information on the individual components from the double and multiple star systems, is made. The grid step errors are identified.
