[IGSSTATION-5037] GODE/GODZ antenna LNA failure

[Stowers, David A (3350)]

Author: Dave Stowers


Dear Colleagues, 

Please be advised that after a very long service interval, a portion of the choke ring
antenna providing signal to sites GODE and GODZ has been determined to have failed.

As this site was undergoing an in-situ dome calibration period, the failed LNA is being replaced
and the antenna will be then returned to it's mount with no other modifications so that the calibration can
hopefully continue. The expected repair is scheduled for completion next Wednesday.

Please also note that two new deep drilled braced monuments have been installed on-site (GODN/GODS)
as will be announced in a separate message. Data from these monuments is available at CDDIS.

Best regards,

-dave
