Abstract
Analyses of the orbits of the satellites of the Global Positioning System (GPS) by participants in the International GPS Service (IGS) (Mueller and Beutler, 1992) provide daily observations of high-accuracy polar motion. These data are used routinely by the International Earth Rotation Service (IERS) (see, for example, IERS Annual Report for 1993). The GPS data have also been analyzed by some centers to produce estimates of UT1-UTC. Currently, the UT1-UTC data are not used because of large systematic errors, but this situation is expected to change in the near future due to the results of ongoing research.
