Rapid Service IGS Orbit Combination - Week 0784   (Jan 15, 1995 - Jan 21, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07847.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 Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:

 IGS07840-6.SP3  IGS GPS ephemeris files for days 0-6, week 0784 in SP3 format.
 IGS07847.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07847.SUM    Complete report.


REMARKS on IGS Rapid Service 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. 

4. PRN31 was set unusable from day 0 (Jan 15) starting at 22:15 
   (ref. NANU 010-95015) until day 1 (Jan 16) at 21:52 (ref. NANU 011-95016).
   PRN31 was also set unsuable from day 2 (Jan 17) starting at 17:05 until
   day 3/wk785 (Jan 25) at 20:13 (ref. NANU 015-95025).
   The large clock RMS seen for COD and NGS on day 3 are due to broadcast not 
   acknowledging on time a jump on PRN31 of about 2 usec detected by all 
   centres.

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
                    -------------+------+--------
                     3 (Jan 18)  |  01  |  EMR                     

6. 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
     ------------+----------+-----+------------------------------
      3 (Jan 18) | 00:00:00 |  23 |   ALL    | Modelling Problems
      6 (Jan 21) | 00:00:00 |  31 | ESA,IGS  | Modelling Problems

7. 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 A were used.
