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

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

 Description of analysis for period 1994 Jun 12 - Jun 18
                                                        (week 0753)
 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: - PERT was down on days 168 and 169, for the reasons see
               our IGS mail 0638.
             - ALGO data was not available for day 169, see IGS mail
               0643.
             - From day 165 on we obtain bad orbit comparisons for
               PRN12. As announced in CANSPACE mail, PRN12 has entered
               into an elicpse season, which will last until day 187.
               During that time PRN12 is set unusable by USNO.

 4. GROUND STATIONS: Altamimi and Boucher, IGS Mails 421 and 430,
                     ITRF92 at 1994.0 and localtie.tab.
