ADVISORY
========
Site name : ST JOHN'S
4 char ID : STJO
Monu inscription : 920000
Domes number : 40101M001
Following the problems at STJO last week some of the equipment have been
replaced. The changes are indicated in the log that follows. Note that tracking
has resumed normally since 00:00 UT on 03-MAR-95 (DOY 62) except for a 3 hour
gap during that day when additional testing was done and corresponding data
deleted.
You should also note that RINEX header information in the files transmitted to
CDDIS for 03-MAR-95 to 05-MAR-95 were not representative of the equipment on
site. New files with revised header information have been transmitted to CDDIS
on 06-MAR-95 21:30 UT. The antenna height has not been affected in these
latest changes, it remains at .100 m since 26-FEB-95.
I hope this information gets through since it appears that there is some
problems with IGSMAIL; a previous transmission of this information as well as
other updates on STJO in the last few days didn't got through by IGSMAIL.
