 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 Apr 10 - Apr 16
                                                        (week 0744)
 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: - Lack of observations for:

                  Satellite PRN13 on DOY 100, 101 and 102. The
                  satellite was tracked again starting on DOY 102
                  around 1200 UTC.

                  Satellite PRN03 on DOY 100 until 1200 UTC and
                  on DOY 103, 104, 105 and 106. According to CANSPACE
                  this satellite 'is expected to be set permanently
                  unusable on day 103 beginning 1500 due to navigation
                  payload shut down in preparation for final disposal'.

                  Satellite PRN06 on DOY 100, 101, 102, 103. According
                  to CANSPACE this satellite was set unusable on DOY 105
                  at 17:15 for up to 72 hours due to manoeuvre. We did
                  not estimate it because the satellite was not tracked
                  after the manoeuvre. The orbit was propagated on
                  DOY 106 after 1930 UTC.

                  Satellite PRN24 on DOY 104. No tracking since 0500
                  until 1500 UTC.

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