 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 Jul 11 - Jul 17
                                                        (week 0705)
 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: With the beginning of week 0705 we started to include ESA-site
             Kiruna (KIRU/9200) into our IGS-processing. With USUD we had
             so much problems, that we excluded it for the whole week, except
             for the last day. Only a very few data was available on some
             days for USUD. When using these data, the whole solutions where
             damaged.

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