Abstract
EGU General Assembly 2011 | Vienna | Austria | 03-08 April Introduction In view of the forthcoming introduction of a new terrestrial reference frame (IGS08) and a new consistent antenna phase center model (igs08.atx) into the processing standards of the International GNSS Service (IGS), the IGS analysis centers (ACs) at the European Space Agency’s Operations Centre (ESA/ESOC) and the Center for Orbit Determination in Europe (CODE) have reprocessed several years of multiGNSS tracking data in order to provide an up-to-date set of consistent satellitespecific antenna phase center offsets (PCOs) and variations (PCVs) for the GLONASS space segment. Both AC solutions were generated according to a rigorously combined multi-GNSS processing scheme ensuring full consistency between the GPS and the GLONASS system. Thereby, the PCOs and PCVs for all receiving antennas as well as for the transmitting antennas of all GPS Block II/IIA/IIR satellites were fixed to their igs08.atx values. The reference frame was aligned to ITRF2008/IGS08. Further processing details are given below (see Table 1).
