Romero, R. Schmid Subject: Call for abstracts for IGS Workshop Plenary #7 *_Thursday February 11th, Plenary 07: Infrastructure and Antenna Calibration_* For this plenary session, and the two related poster sessions we welcome oral presentations and posters covering issues related to IGS infrastructure, and antenna calibration in-line with the descriptions below. *Infrastructure (Nacho Romero)* The IGS Infrastructure is the backbone of all the IGS services, encompassing stations, data formats, data storage, etc. In this session we will cover the current state of the IGS infrastructure elements to provide an overview of the state of the evolving IGS station network, data centers, data formats, station information, etc. Of these important elements the handling of station metadata is being addressed to ensure that the configuration information of all the participating stations can be shared via automated protocols between participating institutions and the IGS Central Bureau. A second essential element in the IGS data handling has been incorporating of all Rinex 3 files into the standard data repositories at all the data centers. The IGS has also incorporated most of the MGEX stations to the regular station network, and we have been increasing worldwide station coverage in the IGS by contacting more station operators currently outside the IGS. The IGS Infrastructure is quickly adapting to encompass new satellite signals, increasing data types and frequencies, and providing better geographical coverage , all of these are very significant areas of interest. *Antenna Calibration (Ralf Schmid)* In July 2015, the absolute IGS antenna phase center model was complemented with conventional and/or manufacturer-specific satellite antenna phase center offset (PCO) values for the new GNSS (Galileo, BeiDou, QZSS, IRNSS). For lack of information on the dependence of the phase center on the observation direction, the corresponding phase center variations (PCVs) were set to zero for the time being. Both PCO and PCV values will have to be replaced by estimates from global GNSS analyses in the coming years. Further effort is also needed with respect to the estimation of GPS satellite antenna corrections. A combined processing of terrestrial and low Earth orbiter data would allow the IGS to provide an independent estimate for the terrestrial scale. Azimuth-dependent PCVs should be considered at the same time. Concerning the receiver antennas, the integration of chamber calibration values (for the new GNSS) into the IGS model as recommended during the last IGS Workshop is still under discussion. Besides, new calibration institutions become operational. In order to avoid systematic errors, there is a need for careful comparisons of independent calibration results. Multipath mitigation or the possible benefit from individual antenna calibrations are other open issues.
