Abstract: We reprocess the Hipparcos Intermediate Astrometric Data of know spectroscopic binaries (retrived from the 9th catalogue of spectroscopic binary orbits, to see whether the orbital inclination, and thus the mass of the secondary, can be derived. Several statistical tests (Pourbaix & Arenou 2001) are used to ensure the reliability of the fit. About 70 systems (originally processed as single stars) out of 863 benefit from the orbital model.
