System-specific systematic errors in earth rotation parameters derived from GPS, GLONASS, and Galileo

The earth rotation parameters (ERPs) are time-variable global geodetic parameters with a purely geophysical origin. Theoretically, the estimates of these parameters should be independent of the satellite constellation used in GNSS processing. Nonethe
