 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 Jan 30 - Feb 05
                                                        (week 0734)
 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:

  - A.S. on from DOY 031 on for all the satellites with the
  exception of PRN13, PRN12 and PRN03.
    For getting better results, especially in our clock solution,
  we have included in our processing four new stations equipped
  with TurboRogues (HOB1, ONSA, PIE1 and TSKB).
    As it is already known, we have detected biases in the CA pseudo-
  range, that depend on the station (receiver) and satellite. We did
  not correct for these biases, but weighted differently the different
  pseudo-ranges to obtain our clock solution.
    We expect errors in the clocks of the GPS satellites to be around
  the 10 ns rms.

  - Manoeuvre of satellite PRN16/SV-16 on 02/02/94 at 10:27:00
  We have estimated the following components in the orbital reference
  frame:

      Radial:        5 mm/s
      Transverse: -222 mm/s
      Normal:       -2 mm/s

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