From Joachim Fri Mar 5 17:28:39 1993 From: Joachim (Joachim) Date: 5 MAR 1993 17:28:39 Subject: [IGSREPORT-162] ESA analysis report (week 0685) Message-ID: *********************************************************************** IGS Electronic Report 5-MAR-1993 17:28:39 Message Number 162 *********************************************************************** From: Joachim Feltens Subj: ESA analysis report (week 0685) ------------------------------------- ------------------------- ANALYSIS CENTRE: ESA/ESOC ------------------------- OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS AT THE ESOC PROCESSING CENTRE FOR IGS J.M.Dow, J.Feltens, T.Martin-Mur, C.Garcia-Martinez Description of analysis for period 1993 February 21 - February 27 (week 0685) 1. SOFTWARE USED: GPSOBS/BAHN-Version 5 2. MODELS USED AND PARAMETERS ESTIMATED/FIXED: For a description of models and parameters used ==> see IGS - Mail 51 For updates of the models and parameters used ==> see IGS - Mail 114 3. REMARKS: This week ground stations MATE, SANT, YAR1 are missing at least several days. Normally we keep these ground stations fixed, i.e. they are part of the ground stations which define our reference frame. According CANSPACE, Anti-Spoofing was switched on 21, 26, and 27 February for several hours each case. So our results are little bit worst at the end of the week, especially the orbit quality of PRN13/SVN09 has sufferend, in spite no drastic signs for this can be found in the corresponding job output. PRN22/SVN22 became active on day 054 (according to our soft- ware outputs). We will include that satellite into our processing with the beginning of week 0686. 4.
