IGS Final Orbit Combination Week 0774             (Nov 06, 1994 - Nov 12, 1994)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07747.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:

 IGS07740-6.SP3  IGS GPS ephemeris files for days 0-6, week 0774 in SP3 format.
 IGS07747.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07747.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07740-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07747.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07747.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 5 (Nov 11) when only PRN15 and PRN28
   were used since the broadcast clock corrections for PRN12 exhibited a 20 ns
   jump that corrupted the weights.

4. There was a maneuver of PRN07 planned for day 4 (Nov 10) (ref.
   NANU 242-94314) that got changed to non-repositioning maintenance (ref. 
   NANU 250-94314). However, all centers have modeled or excluded PRN07 on that
   day. Therefore, the ESA solution which modeled a maneuver is provided for
   PRN07 on day 4 as the combined solution. The NGS solution on that day was
   excluded from the combination based on the assumption that it is an
   extrapolation instead of the actual modeling. An associated accuracy code of
   0 (unknown) was given since there was no redundancy. The ESA, NGS and the
   combined solutions for PRN07 were excluded from the long arc evaluation on
   day 4 due to unrealistic RMS caused by the maneuver.

5. Some clock solutions were excluded from combination due to large clock
   shifts or outliers that were biasing the combined clock solution but were
   kept for RMS computation. The following table lists the exclusions:

            Day (Date)  |   PRN    | Centres | Shifts/Outliers
           -------------+----------+---------+------------------
            4 (Nov 10)  | 4,5,6,16 |  ESA    | up to 50 ns.
                        | 17,18    |         |

6. 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  
                    -------------+------+--------
                     0 (Nov 06)  |  28  | EMR    

7. State vector resets were modeled for the following satellites to 
   alleviate the effects of modelling problems, experienced by all centres, 
   in the long arc process:

      Day (Date) |   TIME   | PRN | Centres  | Reason
     ------------+----------+-----+--------------------
      4 (Nov 10) | 10:00:00 |   7 |   ALL    | Maneuver

8. 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.
