From: Robert Duval / NRCan Subject: [IGSMAIL-0897] STJO data posted but use with caution Date: Thu, 2 Mar 1995 10:01:15 PST ****************************************************************************** IGS Electronic Mail Thu Mar 2 10:01:15 PST 1995 Message Number 0897 ****************************************************************************** Author: Robert Duval / NRCan Subject: STJO data posted but use with caution ADVISORY ======== Site name : ST JOHN'S 4 char ID : STJO Monu inscription : 920000 Domes number : 40101M001 STJO data for 28 Feb 95 and 01 mars 95 (DOY 59 and 60) have been forwarded to CDDIS. However, that data should be used with caution. Following equipment change on the 26 feb 95, tracking has been very poor ( difficulties acquiring the satellites, difficulties maintaining lock and numerous breaks in the data). Since many components were replaced on the 26th i.e. receiver, antenna and rubidium clock it has been difficult to identify the cause of the problem. We have now narrowed it down to the rubidium clock. The clock has just been replaced and we are now verifying that tracking will be normal. We will issue a confirmation message when data for that site is back to normal. -- Robert Duval Geodetic Survey Division Tel: (613) 947-2786 Natural Resources Canada (NRCan) Fax: (613) 995-3215 615 Booth Street E-mail: duval@geod.emr.ca Ottawa, Ontario K1A 0E9 ***************************************************************************** [Mailed From: Robert Duval ]
