IGS Final Orbit Combination Week 0743             (Apr 03, 1994 - Apr 09, 1994)

Contacts: F. Lahaye ([email-masked]), J. Kouba ([email-masked])

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07437.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:

 IGS07430-6.SP3  IGS GPS ephemeris files for days 0-6, week 0743 in SP3 format.
 IGS07437.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07437.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07430-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07437.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07437.SUM    Rapid Service complete report.

REMARKS on IGS Final Orbit Combination:

1. 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. Starting with the GPS week 742 a new clock combination scheme was put in
   place. Now the clock solution alignments to the GPS time use only non-SA
   broadcast clock corrections (currently PRN 12, 15, 20) and the centre clock
   weights are determined from the fit RMS of this alignment. In this
   way the quality of the clock alignments (to the GPS time) are not affected
   by SA and more realistic and objective weights are determined and used in
   the clock combination, provided the non-SA satellites are representative of
   each centre clock solution quality.

4. Combined satellite clock corrections were produced for PRN03 although this
   satellite is close to end of life.

5. Although listed in the header of the submitted SP3 file, PRN13 solution from
   NGS on day 6 gives zero coordinates for all epochs. This solution was 
   therefore excluded from all processing and figures (RMS included) in both
   combination and long arc evaluation.  PRN 13 had very sparse tracking data on
   that day and only JPL submitted a solution. An accuracy code of 0 (unknown) 
   was given to PRN13.

6. Broadcast clock corrections show late acknowledgment of clock resets for
   PRN13 and PRN20 on day 0 (Apr 03) and PRN13 on day 1 (Apr 04).

7. PRN20 on day 0 (Apr 03) was excluded from the clock weights determination
   since the broadcast clock corrections did not reflect what was observed by 
   the Analysis Centres.   

8. One clock solution was excluded from combination due to large clock
   shifts or outliers that were biasing the combined clock solution but was
   kept for RMS computation. The following table lists the exclusion:

            Day (Date)  |  PRN   | Centres | Shift/Outliers
           -------------+--------+---------+---------------
           5 (April 08) |  12    |  JPL    | ~100 nanosec.

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

               Day (Date)   | PRN   | Centres  
               -------------+-------+--------
               2 (April 05) | 21,28 | NGS

               3 (April 06) | 22,24 | NGS  
               4 (April 07) | 04    | NGS
               5 (April 08) | 18,25 | EMR
               5 (April 08) | 22,24 | NGS
