Initial VLBI Data Analyses at the National Geographic Institute of Spain
Abstract
The National Geographic Institute of Spain (IGE) has been taking part in geodetic VLBI since 2008 through the participation of the Yebes 40-meter radio telescope in VLBI observation campaigns. It also encourages the continuous development of the RAEGE project for an Atlantic Network of Geodynamical and Space Stations, as part of the VLBI Geodetic Observing System. Currently, IGE is expanding its contribution to geodetic VLBI by taking its first steps in VLBI data analysis. We present in this work the results of the initial analyses carried out using VieVS 3.0 (University of Vienna) and Where (Norwegian Mapping Authority) as processing software. One-year series of Earth Orientation Parameters obtained from R1 and R4 IVS sessions are compared with IERS 14 C04 series and those from other VLBI Analysis Centers. In addition, secondary VLBI products such as zenith troposphere delay and clock offsets are also compared with GNSS-based products for stations in which VLBI and GNSS antennas' co-location make this analysis possible.
