 OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS
 AT THE ESOC PROCESSING CENTRE FOR IGS

 J.M.Dow, J.Feltens, T.J.Martin-Mur, C.Garcia-Martinez

 Description of analysis for period 1993 Sep 26 - Oct 02
                                                        (week 0716)
 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 and
                                                      see IGS - Rep. 224,277
 3. REMARKS: - We have included the new satellite SV-35/PRN05 in our
               processing.
             - Manoeuver of satellite 24 on 27/09/93 (DOY 270)
               at 16:52:30. We have estimated the following components
               in the orbital reference frame:
                 RADIAL          3.3 mm/s
                 TRANSVERSAL  -185.6 mm/s
                 NORMAL         15.3 mm/s
             - Satellite SV-09/PRN13 has been excluded from the
               processing on days 274 and 275. This satellite was
               declared unusable from 12:00 DOY 273 for up to 10 days
               due to maintenance. See CANSPACE mail of 17 Sept 93.

 4. GROUND STATIONS: Boucher and Altamimi, IGS workshop Berne 24-27 March'93
                     IGS/IERS station coordinates in the ITRF91 at 1992.6
