The file contains all available absolutely calibrated receiver antennas, including the following antenna+radome calibrations for 22 antennas (10 calibrations from Geo++ and 12 calibrations from NGS converted to the absolute values): Antenna Radome Sites -------------------- ----- ASH700936A_M SNOW HOLP ROCK TABL ASH700936B_M SNOW BAHR BJFS CRFP VNDP ASH700936C_M SNOW RIOG SCUB WTZA ASH700936D_M SCIS AMMN LBCH SCIP ASH700936D_M SNOW ANTC BUCU COPO COSO COYQ DRAG DUBR FALE HELJ HILO HNLC IQQE ISTA KOUC LHUE MAUI PARC ROCH SUVA TRAB VALP WIDC ASH700936E SNOW HNPT OSJE PTBB WUHN ASH701933B_M SNOW FREE MANZ ASH701945B_M SCIS AZU1 DHLG MBAR MONP PIN1 SIO3 SNI1 ASH701945B_M SCIT GLPS NRIL SFDM ASH701945B_M SNOW HYDE RAMO TEHN ASH701945C_M SCIS INVK KGNI MOBN PIN1 TWTF ASH701945C_M SCIT BREW HALY NAMA ASH701945C_M SNOW BOGI KIRU ASH701946.3 SNOW GOPE LEIAT303 LEIC LEIAT504 LEIS BZRG MALD SVTL TGCV LEIAT504 SCIS HOLB UCLU NOV503+CR SPKE GMSD TPSCR3_GGD CONE SASS STR2 WARN WTZZ TRM29659.00 TCWD GOUG VESL TRM29659.00 UNAV BARH BRMU EPRT ESTI GUAT MANA SSIA TUBI TRM33429.20+GP UNAV ASPA CNMR The satellite antenna z-offsets (satellite-specific) and patterns (block-specific), which are compatible to the given receiver patterns, were determined by the Technical University of Munich (TUM) and GeoForschungsZentrum Potsdam (GFZ) re-analysing 11 years of data. The file contains the mean values of both solutions. During the estimation of the z-offsets the network solution was fixed to the IGb00 system. Therefore the use of the new antenna file should not result in systematic scale changes. The detailed influence of the new model on all the IGS products will be investigated during the next months before the official IGS products will be based on the new antenna models. Up to now GLONASS satellites are not included, but will be added as soon as first estimates are available. We would like to thank Geo++ for providing the antenna+radome calibrations (http://gnpcvdb.geopp.de) to the IGS.
