From Robert Tue Mar 7 12:15:58 1995 From: Robert (Robert) Date: Tue, 7 Mar 1995 12:15:58 PST Subject: [IGSMAIL-0904] STJO TRACKING STATUS (retransmission) Message-ID: ****************************************************************************** IGS Electronic Mail Tue Mar 7 12:15:58 PST 1995 Message Number 0904 ****************************************************************************** Author: Robert Duval / NRCan Subject: STJO TRACKING STATUS (retransmission) 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. -- Robert Duval Geodetic Survey Division Tel: (613) 947-2786 Natural Resources Canada (NRCan) Fax: (613) 995-3215 615 Booth Street E-mail: duval at geod.emr.ca Ottawa, Ontario K1A 0E9 ***************************************************************************** ***************************************** ST JOHN'S (STJO) SITE INFORMATION ***************************************** 0.
