IGS Final Orbit Combination Week 0825             (Oct 29, 1995 - Nov 04, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08257.SUM).

SOFTWARE:

  The weighted average software used was developed by T. Springer and
G. Beutler during 1993. The GPS long arc orbit analysis software used here for
individual centre ephemeris evaluation was developed by Beutler et al. at the
Astronomical Institute of the University of Bern (AIUB). For more details on
the orbit combination and complete references for both software see:

   Beutler, Kouba, Springer, 1993, Combining orbits of the IGS processing
   centres, in IGS Analysis Centre Workshop, October 12-14, Ottawa, pp 19-55.


PRODUCTS GENERATED:

  The resulting average ephemeris and clocks are output to daily files in SP3
format. The satellite accuracy codes displayed in the header are based on the
weighted RMS for each satellite. Note that each file contains all the
satellites that appear in any of the centre ephemeris files. If a satellite or
centre was excluded from combination, a note in the REMARKS section of this
report will identify the exclusion and the reason.

  The IGS Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:

 IGS08250-6.SP3  IGS GPS ephemeris files for days 0-6, week 0825 in SP3 format.
 IGS08257.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08257.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR08250-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR08257.ERP    Rapid Service earth rotation parameters (ERP).
 IGR08257.SUM    Rapid Service complete report.


REMARKS on IGS Final Orbit Combination:

1. The centres used in the clock combination are COD, EMR, ESA, GFZ and JPL. The
   other centres are excluded because they either provide broadcast clocks (NGS)
   or clock corrections are not provided (SIO).  The clock information not
   used is still compared to combination for completeness.  
   The value of 999999.999999 microseconds, according to the sp3 format 
   convention, is used to signify that no clock solution is available and 
   therefore must not be used.

2. Only the GFZ "exact" clock corrections (one epoch out of two) are included
   in the combination and RMS computation (no "interpolation" values).

3. Centre clock weights were determined using the following non-SA satellites:
   PRN12, PRN15 and PRN28. 

4. PRN09 was set unhealthy on day 6 (Nov 04) from 05:00 until 05:29 (NANU
   235-95309).  This explains higher clock RMS for NGS on day 6.

5. Some orbit solutions were excluded from the combination because they were
   biasing the weighted average (generally indicated by long arc RMS). 
   They were still used for statistics computation.  The following table 
   lists the exclusions:

                     Day (Date)  | PRN  | Centres  
                    -------------+------+--------
                     6 (Nov 04)  | 09   | EMR,NGS

6. Centre specific UT1-UTC values for ESA, NGS and SIO were not used in the 
   long arc evaluation.  Smaller RMS were obtained when UT1-UTC values from 
   Bulletin B were used.

7. Anti-Spoofing (AS) was switched on at ~00h00 UT on day 3 (Nov 1).
