AB: More than 2 million station-days of GPS position estimates for 909 sites are used to examine the impact of various transformations into ITRF2005. Velocity estimates are obtained after 7, 6, and 3 parameter transformations. The traditional 7 parameter series uses the SLR geocenter and VLBI scale from ITRF2005. The 6 parameter series uses the SLR geocenter but keeps the GPS scale. The 3 parameter series uses both the GPS geocenter and scale. Results indicate that as GPS improves over time, less transformation parameters are necessary.
