The Earth Orientation Parameters (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 (24 GHz, 1.2 cm). We 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 S/X-band. We compare our K-band EOP computed with two analyses software packages (Calc/Solve and VieVS) to the IERS C04 data.
