We discuss the determination of pole-position variations from the analysis of 23 days of Global Positioning System (GPS) data continuously collected with a globally distributed, 21-station network. The comparision of the estimated pole positions from these data with results from 11 very long baseline interferometry (VLBI) experiments conducted during this same interval yields weighted root-mean-square differences about the mean differences of 0.5 mas for X- and Y-pole position estimates from an analysis using single-day arcs, and 1.0 and 0.8 mas from an analyis using three weekly multiday arcs. These results are of sufficient quality that GPS could provide an alternative technique to VLBI and satellite laser ranging (SLR) for regular monitoring of high-time-resolution variations in the position of the Earth's rotation axis. ¿American Geophysical Union 1991
