 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 18 - Jul 24
                                                        (week 0706)
 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: From the beginning of 0706 on, we have included SV-39/PRN09
             into our routine IGS-processing.

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