The description of the first version of the General Compiled Catalogue
of Absolute Proper Motions (GPM1) for a sample of stars,
derived with respect to galaxies within the plan called Catalogue of Faint
Stars (KSZ, Deutch 1952), is presented.
The principal aim of the GPM1 construction was to provide absolute
proper motions of stars to determine the rotation of the HIPPARCOS system.
The GPM1 catalogue contains 977 Input Catalogue stars
with V magnitudes 
in 180 fields north of -25 degrees
of declination. The accuracy of the proper motions is 8 mas/yr
(milliarcseconds per year). Comparison of proper motions of GPM1
with those of the PPM and ACRS was performed and analyzed with respect
to systematic errors caused by spurious rotation of the FK5 system.
The standard errors show that the rotation may be determined with
an accuracy better than 1 mas/yr.
