Current Dorne Margolin T antenna (s.n.173) will be replaced with one with the RFI Low Noise modification (s.n.386). Although no significant variation of the antenna phase centre is expected from that change, overlapping tracking procedures will be in place to ensure that any variation can be traced. IGS community will be informed of any variation following analysis of these data.
