Rapid Service IGS Orbit Combination - Week 0833   (Dec 24, 1995 - Dec 30, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08337.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 resulting x and y earth rotation parameters (ERP) associated with the IGS
ephemeris files are computed using a weighted average of all available centres 
(weights are those from the orbit combination). These values are supplemented 
with the current IERS Bulletin A UT1-UTC values. 

  The Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:

 IGS08330-6.SP3  IGS GPS ephemeris files for days 0-6, week 0833 in SP3 format.
 IGS08337.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08337.SUM    Complete report.


REMARKS on IGS Rapid Service Orbit Combination:

1. The centres used in the clock combination are COD, EMR, ESA, GFZ and JPL. The
   other centres are excluded because they either provide broadcast clocks (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. 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 (Dec 27) | 00:00:00 |  05  |   ALL    | Modeling problems
       4 (Dec 28) | 00:00:00 |  20  |   ALL    | Modeling problems
       4 (Dec 28) | 00:00:00 |  22  |   ALL    | Modeling problems
       4 (Dec 28) | 00:00:00 |  23  |   ALL    | Modeling problems


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
                    -------------+------+--------
                     4 (Dec 28)  |  23  | ESA      

6. Centre specific UT1-UTC values for ESA were not used in the
   long arc evaluation.  Smaller RMS were obtained when UT1-UTC values from
   bulletin A were used.

7. NGS solutions were not used in the combination since they were not available 
   on CDDIS at the time of this combination. These will be used in the final 
   combination.  

   On days 0-6, broadcast clock corrections were still used to align each 
   centre satellite clock corrections to GPS time despite of the missing NGS
   solutions (which usually are used for the alignment to the broadcast GPS
   time).
