 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 Nov 07 - Nov 13
                                                        (week 0722)
 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: - AS on days 8 and 9 Nov (312 and 313).

             - Satellite SV-09/PRN13 was scheduled to be unusable on
               day 308 beginning 0000 UTC until day 349 at 0000 due
               to maintenance. The precise orbit of this satellite is
               affected the whole week by periods of several hours
               without observations.

             - Satellite SV-11/PRN03 was unusable on days 8 and 9 Nov
               (312 and 313) for several hours. (See CANSPACE mail
               93-11-09).

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