The new catalogue of Positions and Proper Motions (“PPM”) was compiled to replace the AGK3 and SAO catalogues as an astrometric reference on the northern celestial hemisphere. It provides more than 180 000 reference stars, is on the system of FK5 (J2000.0) and has a higher accuracy than the two older catalogues.

Some properties of PPM and its High-Precision Subset are presented.
