IGS Final Orbit Combination Week 0776             (Nov 20, 1994 - Nov 26, 1994)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07767.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:

 IGS07760-6.SP3  IGS GPS ephemeris files for days 0-6, week 0776 in SP3 format.
 IGS07767.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07767.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07760-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07767.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07767.SUM    Rapid Service complete report.

REMARKS on IGS Final Orbit Combination:

1. The centres used in the clock combination are EMR, ESA, GFZ and JPL. The 
   other centres are excluded because they either provide broadcast clocks 
   (COD, 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, except on day 4 (Nov 24) when only PRN12 and PRN15
   were used since the broadcast clock corrections for PRN28 exhibited a 20 ns
   jump that corrupted the weights.

4. The large clock RMS for COD and NGS for days 0 to 3 (Nov 20-23) are due to
   the broadcast clocks for PRN19 which did not reflect large clock drifts (few
   micro-sec.) detected by all centres for that satellite. A NANU was issued
   (ref NANU 261-94327) declaring PRN19 unusable for that time period.

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  
                    -------------+------+--------
                     2 (Nov 22)  |  04  | NGS    
   
   Moreover, NGS solution for PRN04 was excluded from the long arc evaluation
   on day 2 due to unrealistic RMS caused by this solution.

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.
