IGS Final Orbit Combination Week 0755             (Jun 26, 1994 - Jul 02, 1994)

Contacts: Y. Mireault (mireault at geod.emr.ca), Kouba (kouba at geod.emr.ca),

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07557.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:

 IGS07550-6.SP3  IGS GPS ephemeris files for days 0-6, week 0755 in SP3 format.
 IGS07557.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07557.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07550-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07557.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07557.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. PRN12 was excluded from the clock weights determination on day 3 (Jun 29)
   since neither COD nor NGS submitted broadcast clock corrections for that
   day. Note that PRN12 was set unhealthy for the whole week (ref. NANU 
   182-94192).

5. Some clock solutions were excluded from combination because they were
   biasing the combined clock solution (as indicated by clock comparisons),
   but they were kept in the clock RMS computation. The following table
   lists the exclusions:

        Day (Date) |     PRN      | Centres | Shifts/Resets
       ------------+--------------+---------+------------------------
        2 (Jun 28) |      4       |   ESA   | up to ~ 350 ns
                   |    15,22     |   GFZ   | up to ~ 40 ns 
                   |  1,16,21,27  |   JPL   | up to ~ 80 ns 
        3 (Jun 29) |  1,7,27,28   |   ESA   | up to ~ 90 ns 
        4 (Jun 30) |     ALL      |   GFZ   | up to ~ 30 ns 
                   |     ALL      |   JPL   | up to ~ 40 ns
        5 (Jul 01) |     ALL      |   JPL   | up to ~ 60 ns 
        6 (Jul 02) |     ALL      |   JPL   | up to ~ 60 ns 

6. The SIO orbit solutions for this week were excluded from combination due to
   their large rotations in Y-axis that were biasing the orientation of the
   combined orbits.  Other orbit solutions were excluded from combination
   because they were biasing the combined solution (as indicated by long arc
   RMS), but they were kept in the orbit RMS computation. The following table 
   lists the exclusions:
 
                    Day (Date)     |  PRN    | Centres
            -----------------------+---------+--------
                   2 (Jun 28)      |  4,9    | NGS

                   3 (Jun 29)      |   9     | NGS  
                   5 (Jul 01)      |   4     | JPL,NGS  
               0-4 (Jun 26-Jun 30) |  ALL    | SIO
                   5 (Jul 01)      |  ALL    | SIO (Missing)
                   6 (Jul 02)      |  ALL    | SIO

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  
               ------------+----------+-------+--------
                4 (Jun 30) | 00:00:00 | 05,12 |  ALL
                6 (Jul 01) | 00:00:00 | 23    |  ALL

8. UT values from Bulletin B were used in the long arc evaluation for JPL 
   (discontinuities found in its UT series on day 1/Jun 27), ESA and NGS 
   (smaller RMS).  Also, erp values from Bulletin B were used in the long arc 
   evaluation for SIO since day 5/Jul 1 was missing from its erp file.

Table 3: Daily fit for each satellite and each centre resulting from weighted
         average combination and from long arc orbit dynamics (7-day). The
         first IGS column gives resulting satellite accuracy measures found in
         SP3 header. The last IGS column gives the RMS fit of the IGS orbit
         when processed through the 7-day arc evaluation.
         "E" flags eclipsing satellites.
         Units: cm.
