Note that the SVN number was assigned according to an IGS Workshop recommendation (see IGSMAIL #7252) to 857 (changed from 757 to 857). The following PRELIMINARY phase center offset (PCO) values were assigned: PCO_X = -54.5 cm PCO_Y = 0.0 cm PCO_Z = 245.0 cm 2) The following decommission date has been added: ? R15 (716):? 23 November 2018 3) Five additional antenna type calibrations have been added that were performed by Geo++ GmbH: ???? - Three robot calibrations provided by Javad GNSS Inc. have been added: ??????
