  In anticipation of the Gaia astrometric mission, a large sample of
spectroscopic binaries has been observed since 2010 with the SOPHIE
spectrograph at the Haute--Provence Observatory. Our aim is to derive the
orbital elements of double-lined spectroscopic binaries (SB2s) with an accuracy
sufficient to finally obtain the masses of the components with relative errors
as small as 1 % when the astrometric measurements of Gaia are taken into
account. In this paper we present the results from five years of observations
of 10 SB2 systems with periods ranging from 37 to 881 days. Using the TODMOR
algorithm we computed radial velocities from the spectra, and then derived the
orbital elements of these binary systems. The minimum masses of the components
are then obtained with an accuracy better than 1.2 % for the ten binaries.
Combining the radial velocities with existing interferometric measurements, we
derived the masses of the primary and secondary components of HIP 87895 with an
accuracy of 0.98 % and 1.2 % respectively.
