A direct combination of the positions given in the HIPPARCOS catalogue
with astrometric ground-based catalogues having epochs later than 1939
allows us to obtain new proper motions for the 1535 stars of the Basic
FK5. The results are presented as the catalogue Proper Motions of
Fundamental Stars (PMFS), Part I. The median precision of the proper
motions is 0.5 mas/year for 
and 0.7 mas/year
for 
. The non-linear motions of the photocentres of a
few hundred astrometric binaries are separated into their linear and
elliptic motions. Since the PMFS proper motions do not include the
information given by the proper motions from other catalogues
(HIPPARCOS, FK5, FK6, etc.) this catalogue can be used as an
independent source of the proper motions of the fundamental
stars.
