The Polar Motion Derived from Both Time and Latitude Observations

The coordinates of the pole were derived from both time and latitude observations made at eight observatories from 1962 to 1964. The differences between these results and the ILS results show an annual variation. After removal of this term the standard deviation is about ±0′′.03 for thex- andy-components. Corrections to the adopted longitudes and latitudes are obtained and these agree closely with those obtained by the BIH.
