IGS Final Orbit Combination Week 0758             (Jul 17, 1994 - Jul 23, 1994)

Contacts: Y. Mireault ([email-masked]), Kouba ([email-masked]),

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07587.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:

 IGS07580-6.SP3  IGS GPS ephemeris files for days 0-6, week 0758 in SP3 format.
 IGS07587.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07587.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07580-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07587.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07587.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) is 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. 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 | Shift/Outliers
           -------------+-----------------+-----------------------
            1 (Jul 18)  |  All  |   JPL   | up to ~ 60 nanosec.

5. PRN28 (along with PRN 12,15 and 20) on days 2-6 (Jul 19-23) was included in 
   the clock weights determination since its Selective Availability (SA) was 
   turned off on these days.

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

                     Day (Date)  | PRN  | Centres  
                    -------------+------+--------
                     0 (Jul 17)  |  20  |  GFZ 
                     0 (Jul 17)  |  24  |  EMR 
    
7. Centre specific UT1-UTC values for ESA and NGS were not used in the long arc
   evaluation.  Smaller RMS were obtained when UT1-UTC values from Bulletin B 
   were used.
