"Earth orientation parameters estimated from K-band VLBA measurements";
Poster: 24th Meeting of the European VLBI Group for Geodesy and Astrometry,
Gran Canaria, Spain;
The Earth Orientatio nParameters (EOP) which connect the Terrestrial and Celestial Reference Frame are regularly estimated by Very Long Baseline Interferometry (VLBI). The UT1-UTC and nutation components of EOP can only be measured using the VLBI technique. Until recently, published VLBI estimates of EOP were based solely on observations from the S/X frequency band. We present VLBI estimates of EOP from an observing frequency independent of the traditional SX-band using Very Long Baseline Array (VLBA) measurements at K-band (24GHz,1.2 cm). We will have over two years of regular VLBA experiments conducted with telescopes located in U.S. territory. We investigate the potential of K-band VLBI to produce more accurate EOP because of its reduced source structure effects relative to SX-band. We compare our K-band EOP computed with two analyses software packages (Calc/SolveandVieVS) to the IERSC04 data.
