 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 May 23 - May 29
                                                        (week 0698)
 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: For day 147 (27 May 93) a manoeuvre has been announced for
             SV-22/PRN22 (CANSPACE mail of 20 May 93). We detected the
             manoeuvre at 11:29 UTC on day 147 and estimated a velocity
             increment of 38.1 <mm/sec>.

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