Establishment of Plate Motion Model by the Integrated Data of GPS and VLBI

This paper derives a plate motion model called GVM1 based on space geodesy techniques by the integrated data of GPS and VLBI. After selecting the proper stations of GPS and VLBI, establishes the plate motion model and unifies the reference frame of GPS and VLBI, resolves the relative Euler vector among plate north American, Eurasian, Pacific, south American and etc. Comparison between GVM1 and the geological plate motion model NUVEL-1A indicates that the plate motions from space geodetic observations are generally consistent with those from geological observations. The EURA-NOAM Euler pole from space geodetic observations is near to that of NUVEL-1A; the Australia plate has been steady in recent years; those stations located in the boundaries and joints could not represent the south American plate motion; the Pacific Euler pole relative to another plate pairs is consistent with the geological model, which indicates that the plate motion Euler vectors are improved greatly by the integrated data of GPS and VLBI.
