Content-Type: text/plain; charset="us-ascii" Sender: owner-igsstation Precedence: bulk ****************************************************************************** IGS Station Mail 11 Mar 11:54:41 PDT 2008 Message Number 2138 ****************************************************************************** Author: Pierre Uhrich (LNE-SYRTE, Observatoire de Paris) Dear Colleagues, In anticipation of maintenance work on the H-Maser used as reference clock by the OPMT IGS Station, scheduled to start in a few weeks, we have changed today for another H-Maser, as can be seen in the new OPMT log file here joined. In consequence, there will be a large gap in the today observation files (DOY 071), as such a change requires the measurement of all the delays involved for Time Metrology applications. Please find hereafter the new OPMT log file, which contains some information about the new clock signal used starting today. Best regards. P. Uhrich -- =============================================================== Dr Pierre Uhrich Pierre.Uhrich@obspm.fr Inginieur-chercheur LNE Equipe Mitrologie du temps LNE-SYRTE, Phone: + 33 (0)1 40 51 22 17 UMR CNRS 8630, Fax: + 33 (0)1 43 25 55 42 Observatoire de Paris, 61 avenue de l'Observatoire, F-75014 Paris, France. =============================================================== OPMT Site Information Form (site log) International GNSS Service 0.
