The receiver Trimble 4000SSE with antenna Trimble 4000ST L1/L2 Geodetic
(TRM14532.00) was replaced by the restored receiver Ashtech Z18 with
new antenna Ashtech Choke Ring GG P/N 701946-02 REV 3 (ASH701946.023 SNOW).
End of Trimble receiver operation : 04-OCT-2000 13:00 UT
Start of Ashtech receiver operation : 04-OCT-2000 13:30 UT
The ARP of the new antenne is on the same point as the ARP of the old antenne.
The update site information form was sent to IGSCB and is attached.
