Contribution of the VLBA Network to Geodynamics

  A decade of observations in geodetic mode with the VLBA network gave 
valuable results. Approximately 1/5 of all geodetic observations are 
recorded in VLBA mode and processed at the Socorro correlator. 
Ten years of observations allowed us to reliably measure slow intra-plate 
motion of the VLBA stations located on the North-American plate. It also
helped us to achieve scientific objectives of geodetic programs: verify models 
of harmonic and anharmonic site position variations caused by various 
loadings, improve models of core-mantle boundary, investigate mantle rheology 
and solve other tasks.
