Based on data of latitude observations from 41 stations and observatories, the secular and periodic components of the polar motion were separately derived. A system of coordinates of the pole, with origin at the mean pole of 1968.0, called JYD, was set up and the coordinates for the year 1949.0 – 1976.0 are given.
